The Safe Withdrawal Rate Series - Early Retirement Now (2024)

One of the most important topics in financial planning is how to transform an initial portfolio into a safe and sustainable retirement income stream. I’ve put a lot of thought into this topic and published 50+ posts on my blog. To make my research more accessible, I created this “landing page” for everyone interested in my Safe Withdrawal Rate Series.

Should you read from the beginning to the end? Just because I wrote this comprehensive series in this order doesn’t mean that one should read it in that order. Keep in mind that this whole series was a learning experience for me as well, so reading parts 1 through the end will seem a bit jumpy at times. In fact, a lot of the posts came about because readers suggested I check out certain sub-topics, and all that came about in random order. If I were to write this series again today, from scratch, with everything I know today, or if I were to write a book, I would obviously structure this very differently. It would be unfair to new readers to make them go through the entire series! This convinced me to write this new page so newcomers feel less intimidated starting their own thought process on Safe Withdrawal Rates!

How do I even get started with the Safe Withdrawal Rate Series?

Great question!If you’re completely new to FIRE, maybe start with The Basics of FIRE as an introduction to Financial Independence and Early Retirement.

If you have already graduated from the FIRE basics, you will likely look for insights on sustainable withdrawal rate calculations. When I was at that point, I wrote Part 1 – Introduction: This post sets the stage and explains the similarities and differences between my study and the Trinity Study. I replicate some of the Trinity Study results but also generalize the results to make them applicable to the FI/FIRE crowd; most importantly, I look at longer retirement horizons. If you have already read the Trinity Study, you are already skeptical about the simple naive 4% Rule, and you like technical stuff, then sure, start with this one. But to make this series more accessible, palatable, and enjoyable to a wider audience, I also wrote some high-level posts without much technical and math mumbo jumbo. Maybe you read those first to get an appetite:

  • Without diving into any math, you might enjoy these two as your first post: Part 26 – Ten Things the Makers of the 4% Rule Don’t Want You to Know and Part 50 – Ten Things the “Makers” of FIRE Don’t Want You to Know. As the titles suggest, these are tongue-in-cheek posts where I debunk some of the myths surrounding FIRE and the 4% Rule.
  • If you attended the April 2018 CampFI in Virginia, where I was one of the presenters, you’d recognize much of the material inPart 27 – Why is Retirement Harder than Saving for Retirement?: Another more philosophical, not-so-technical post, perfectly suited for folks trying to get started. Probably you’ve heard about MMM’s Shockingly Simple Mathand JL Collins’ Simple Path to Wealth. But the simplicity ofaccumulating assets can’t be so easily extrapolated into the withdrawal stage. That phase is much more complicated, and the reason why I have written so many parts on this topic!
  • Part 32 – You are a Pension Fund of One (or Two). Compare and contrast our personal challenges to those of large corporate and public pension funds. I found many aspects of running my own (early) retirement finances – essentially a pension fund with two beneficiaries that are much more complex than running a pension fund for thousands of beneficiaries!
  • New to the site here? Do you think that rigor and math don’t belong in retirement planning? Why not just wing it? In Part 46, I detail my thought process and why I like to perform my careful, customized, and rigorous retirement withdrawal simulations, not despite but exactly because we face so many uncertainties in retirement. But we don’t have to overdo the precision either! In the follow-up post, Part 47, I go through a few case studies and show when it’s OK to wing it and when it’s time to worry about those nitty-gritty details of the withdrawal rate analysis.
The Safe Withdrawal Rate Series - Early Retirement Now (1)

OK, after the intro, what else would you want to read? Maybe you found interesting sub-topics and relevant links already when reading through Part 26 or Part 50. But I also present all the remaining posts as they fall into several major themes. And don’t worry; I also give a few suggestions on what to read when at what stage in your FIRE journey later in the summary below…

Introduction to Sequence of Return Risk

Why are we even worried about running out of retirement money? Over the long haul, the stock market should return much more than 4%. And a retirement horizon of 30 years for a traditional retiree and 50+ years for an early retiree certainly qualifies as long-run, right? Well, not so fast! I learned from my historical simulations that you can still run out of money even if your 30-year or even 50-year average return was above your withdrawal rate. If returns were bad enough initially and you keep withdrawing through the bear market, there is a chance you will deplete your investment portfolio so severely that even the subsequent bull market and recovery will not save you – the sequence of returns matters. Low returns early on are poison to your retirement finances. It’s the opposite of Dollar-Cost Averaging; you sell more shares when prices are down!

So, no series on Safe Withdrawal Rates would be complete without at least some treatment of Sequence of Return Risk (sometimes also called “Sequence Risk”). That’s what I do inPart 14 and Part 15. I go through some numerical examples, first with “made up” return data and then with actual historical market data to showcase how detrimental Sequence Risk can be. None of this is required reading for a successful (early) retirement, but it’s a nice reference to have!

Also, you might check out my podcast appearances on the topic. All really low-tech with no math degree required:

A question I keep getting: Is there ever a time when we can stop worrying about Sequence Risk? Unfortunately, Sequence Risk will be with you for longer than the often-quoted 5-10 years. See Part 38 for details.

One “solution” I hinted at in 2017: If a saver and retiree could team up where retirement income and retirement savings exactly balance each other so that their aggregate cash flows look like a Buy-and-Hold investor, we could certainly eliminate Sequence Risk. See Part 53. But there are certainly some bureaucratic hurdles to setting up what looks like a P2P pension fund.

The effect of Supplemental Cash Flows (Social Security, Pensions, etc.) on Safe Withdrawal Rates

Social Security and other (almost) guaranteed income in retirement, like pensions and annuities, can greatly enhance retirement security. But how much of a difference can a future payment make to today’s annual withdrawal amount? This is one of the key reasons why Safe Withdrawal Rate Rules are really only Rules of Thumb!We each need a personalized financial analysis to determine our sustainable withdrawal rate. A 30-year-old early retiree with relatively modest expected Social Security benefits many decades in the future has a lower safe withdrawal rate than a 50-year-old early retiree expecting generous Social Security benefits in only a little bit over a decade. How much of a difference does that all make? Well, I studied this in great detail, once in a really early post, Part 4, and then again inPart 17.

You can also use a tool I provide in Part 56 to evaluate the net present value (NPV), internal rate of return (IRR), and crossover (to profit) points of annuities, pensions, and Social Security strategies. I do this all from an actuarial point of view, independent of the withdrawal rate analysis. For example, we can debunk the popular myth that deferring Social Security yields an extra return of 8% a year. Once you factor in conditional survival probabilities, deferring benefits’ internal return on investment (IRR) is roughly in line with TIPS real interest rates. But healthy individuals with a higher-than-average life expectancy can push the real, inflation-adjusted IRR to 3% or more. Not quite a stock market return but for a guaranteed income investment, 3% plus inflation is quite attractive.

How would your Social Security Timing interact with Sequence Risk? I explore that issue in Part 59. There appears to be a persistent myth about claiming Social Security early to hedge against Sequence Risk. But alas, the historical worst-case scenarios (1929, 1964-1968) generated market drawdowns long enough that claiming benefits a few years earlier would not make a difference. Quite the opposite, claiming later and securing the maximum benefits for the long haul performed better in historical simulations.

Why the Trinity Study success/failure probabilities don’t easily apply to you and me

My main “beef” with the Trinity Study? Even if your personal financial situation exactly fits the model assumptions of the Trinity Study – a 30-year horizon and no additional cash flows – I’d not take the Trinity Study success probabilities very seriously for the following reasons:

  • Part 2 – Capital Preservation vs. Capital Depletion: Do you want to leave a bequest? Do you want to leave your entire principal intact instead of exhausting your nest egg? Then the 4% Rule may no longer be sustainable because it was designed with capital depletion in mind. This post looks into how much of a haircut it takes to make the 4% Rule water-tight again when you have a more aggressive final net worth target than $0.00! This post is also relevant for everyone planning a longer horizon than 30 years. Remember, the Trinity Study would consider a final net worth of $0.01 after 30 years a success. Not very useful if you have a 50-year horizon!
  • Part 3: Equity Valuation: After a 10-year-long equity bull market and high equity valuations (and low bond yields), you will face a higher failure probability with the 4% Rule than the Trinity Study may suggest.But does that mean that I can’t retire at all? Do I have to wait until equity valuations “normalize” again? Not at all; I show that with a withdrawal rate in the 3.25-3.50% range, you would have survived even during the most catastrophic historical market conditions!
  • Part 6 – A 2000-2016 case study (Welcome to the Potemkin Retirement Village): Maybe you’ve heard/read that the year 2000 retirement cohort is doing just fine even in light of the deep bear markets in 2001-2003 and 2007-2009. That’s not exactly true, and I got the numbers to prove it!
  • Part 22 – Can the “Simple Math” make retirement more difficult?: This is a post very relevant to folks in the FIRE community. If we all pull the plug and (early-)retire the minute we reach a certain savings target, e.g., 25x annual expenses, we could potentially face a much higher failure rate than what’s quoted in the Trinity Study. The Trinity Study calculates the unconditional probability of having randomly retired over the last century or so. But retiring conditional on reaching a savings target, often after a long bull market run, is a completely different ballgame.This is clearly related to Part 3, see above, but it’s still a new and unique angle!

Calculate your own personalized(!) Safe Withdrawal Rate with a free Google Sheet

What does all of this Safe Withdrawal research really mean for me personally?Nobody wants to read just a bunch of academic-style research on this topic. The problem I always had with the existing body of research, whether it’s from academics or practitioners, is thatmy personal financial situation looks completely different from their “model household.” I like to be able to make adjustments for my specific situation, for example…

  • A 50 or even 60-year horizon. Early retirees should model a very long retirement. The joint life expectancy of a couple retiring in their 30s or 40s necessitates a much longer horizon than the 30 or even 40 years often used in retirement calculators.
  • I like to be able to account for additional future cash flows, both positive (Social Security, a small pension, even a little bit of blogging income) and negative (college expenses for our daughter, higher healthcare costs when older, etc.).
  • Leave a bequest for our daughter when we pass.
  • Account for today’s expensive equity valuations.
  • Study the impact of investment fees.
  • etc.

So, I decided to publish the exact same Google Sheet I use myself (though not with my precise personal data) to gauge my personal Safe Withdrawal Rate using historical market data:

Link to the EarlyRetirementNow SWR Toolbox v2.0

The sheet uses past performance data, not Monte Carlo simulations. So, the simulation results reflect actual investment results that historical retirement cohorts would have experienced. The sheet may not be 100% self-explanatory, so please refer to Part 7for the basic instructions. I also wrote Part 28 to explain all the enhancements added over the years! If the Google Sheet and all the options seem intimidating, my friends Jason and Eric at Two Sides of FI put together a video tutorial on YouTube explaining how to get started with this toolkit. You enter your initial portfolio value, asset allocations, additional future cash flows, etc., and then determine the sustainable withdrawal rates and retirement income using historical data going back 100+ years. And just for the record, the usual disclaimers apply here. Past performance is not guaranteed in the future. Actual investment results may vary!

As a supplementary tool, I also recommend you look at Part 33, where I look at how actuarial calculations may (or may not!) help determine sustainable withdrawal rates. There’s a free Google Sheet tool (link in the post) that uses pretty much the same inputs as in the SWR Toolbox.

For the mathematics geeks, I also provide a small mathematical appendix (Part 8). But again, this is the absolute last post you want to read unless you’re really into math and want to see where those formulas in the Google Sheet came from!

Asset Allocation Considerations to Optimize the Safe Withdrawal Rate

What is the appropriate portfolio mix in your investment portfolio? Clearly, the stock market offers the highest expected return in the long run, but due to Sequence Risk, you might also compromise your portfolio longevity if you invest too heavily in equities and face a deep bear market early in retirement. In my simulations, I find that a balanced portfolio somewhere between 60% and 80% stocks and the rest in intermediate (10-year) government fixed-income securities will thread the needle for most retirement portfolios. But the results will depend on your personal parameters, like your horizon and your bequest target. Please see Part 28 for details on how to start your own simulations to see the effect of your asset allocation on the various investment outcomes.

Dealing with Market Volatility

Withdrawal strategies are never a one-time set-it-and-forget-it. You want to periodically monitor the retirement balance and market performance to see if your plan is still on track, especially once the stock market starts dropping. In the Spring of 2020, during the massive market volatility, I published Part 37, where I go through an example of how I would respond to the inevitable Bear Market.

Also, make sure you read Part 54, published during the 2022 bear market. If you find yourself in a downturn, your investment portfolio may be down, but due to more attractive equity valuations, your sustainable withdrawal rate will now be higher, offsetting at least a portion of the portfolio decline. Thus, your recommended retirement withdrawals may not even fall much. In other words, if you plan to retire during a steep stock market downturn and you multiply your initial portfolio value with the naive 4% Rule, you might seriously short-change your retirement income.

Can flexibility raise your sustainable withdrawal rate?

Why would I sit on my hands if I get unlucky in (early) retirement and my portfolio melts down year after year? If you stubbornly withdraw that same initial amount plus inflation adjustments, the way it’s modeled in the Trinity Study, it’s neither psychologically sustainable nor is it financially sound or mathematically optimal. Rather, everyone would change course at some point: either try to generate some supplemental income or consume less for a while (or a combination of the two). Flexibility is often sold as the panacea against Sequence Risk. I’m certainly not recommending everyone to be inflexible, butI’d argue that flexibility is often overrated:

  • Part 9 and Part 10: Under Guyton-Klinger Rules, you’d systematically lower your withdrawal amounts in response to significant underperformance of your portfolio. And if your portfolio recovers again, you ratchet up your withdrawals. Sounds very intuitive, and in some places, Guyton-Klinger-style rules are sold as the solution against Sequence Risk. But what’s often ignored is that GK Rules can take years, even decades, for your withdrawals (and your spending) to recover to the original level. So, while GK Rules are certainly a useful tool to prevent running out of money in retirement, there are some unpleasant and often hidden and unknown side effects!
  • Flexibility means that we’re using a dynamic and responsive withdrawal strategy. I might replace the risk of running out of money in the long term with very unpleasant short- to medium-term spending levels (see the GK research above!). In Part 11, I study whatcriteria I’d use to weigh different dynamic rules. Rules that take into account both your portfolio level and economic fundamentals (e.g. the Shiller CAPE) seem to make the most sense, which brings us to the next post…
  • … on one really elegant implementation of flexibility: Part 18, where you base the withdrawal amount on the Shiller CAPE Ratio. The advantage: the fluctuations in withdrawal amounts are muted relative to Guyton-Klinger. I also wrote a more in-depth post on flexible/dynamic CAPE-based withdrawal rates in Part 54.
  • Part 23: A reader suggested an intuitive way of dealing with Sequence Risk: If your portfolio balance falls below a certain threshold (e.g., 70% of initial), reduce your spending by, say, 30% (or work to make up the difference) until the portfolio recovers. I point out two serious concerns about this procedure: 1) in the really bad recessions that may imply 20+ years of reducing withdrawals, and 2) even in a not-so-bad bear market, you would have experienced a “false alarm,” i.e., you would have cut withdrawals for years only to find out – in hindsight(!)- that the portfolio would have survived without flexibility.
  • The problem with “flexibility” is that it’s so ambiguous. It’s like playing whack-a-mole; you think you debunked one flexibility scheme, and then people suggest another. So, in Part 24,I look at all the different “flexibility schemes” I could think of and test how they would have performed in historical bear markets. And just to be sure, I also solicited some additional reader suggestions inPart 25. Always with the same results: flexibility eliminates the risk of running out of money in 30 years but raises the risk of long and painful cuts in withdrawals in the short run and medium term! It’s like squeezing a balloon!
  • The kind of flexibility I like: If you’re flexible enough to put in One More Year, you can boost your retirement security substantially! See Part 42.
  • One could tie the withdrawals to the state of the equity market. Specifically, one could tighten the belt and reduce withdrawals when the stock market goes through a deep enough drawdown. In Part 58, I show that this approach has many serious flaws. You create very volatile annual withdrawal amounts and deep and lasting drawdowns of your retirement income.

I’m not saying that flexibility isn’t useful at all. Quite the opposite, in Part 58, I propose a better way of modeling flexibility in retirement to gauge how much of an impact you can make when you are willing and able to temporarily curb your withdrawals, either through spending cuts or a retirement income side hustle.

Alleviate Sequence Risk through Dynamic Asset Allocation! Easier said than done!

The holy grail in finance is tactically shifting your asset allocation to improve investment results. Unfortunately, the average retail investor will not have the ability to reliably time the ups and downs in equity and bond markets. But nevertheless, there are a few simple asset allocation paths that may partially hedge against Sequence Risk…

Prime Harvesting

Part 13 – Prime Harvesting: Many readers suggested this: We can alleviate (never eliminate!!!) Sequence Risk through a smarter, non-passive asset allocation to prevent selling equities through the bear market. Michael McClung suggested one such method in his book Living Off Your Money (paid link). I looked at that method and actually liked it quite a bit. Again, you won’t prevent Sequence Risk, but this is a way to alleviate it slightly!


Though not identical, Prime Harvesting will likely look a lot like an equity glidepath in practice.The idea with a glidepath is that starting with a higher bond allocation initially gives you something of an insurance policy against Sequence Risk because you tend to mostly liquidate your bond holdings initially, right when Sequence Risk is most prevalent. Then, over time, you shift more into stocks when Sequence Risk becomes less of an issue. Thus, on average, you still have a balanced portfolio.

Also, notice that the shift from fixed-income securities to equities is not akin to what actively managed funds do. You don’t rely on proprietary signals. Instead, the shift occurs predictably as a function of time. I slightly prefer this approach over Prime Harvesting because it’s easier to keep track of. SeePart 19 and Part 20!

I’m not a big fan of the “Safety First” approach, i.e., using safe assets like a TIPS ladder and/or an annuity in retirement. At least not exclusively. How about shifting a portion of our portfolio to Safety First assets? I studied that in Part 61. Qualitatively, this boils down to a glidepath again. It can alleviate but not eliminate Sequence Risk.

How about pre-retirement glidepaths? Please see Part 43. Investors with a high enough risk tolerance and some flexibility in their planned retirement date may keep an aggressive portfolio, even 100% equities, until their retirement accounts reach the target level.

Bucket strategies

How about bucket strategies? Not really a panacea for Sequence Risk either, as I show in Part 48. Effectively, they have a lot of similarities with Glidepaths in retirement. But I found that the glidepath simulations looked slightly better than the bucket strategy results. In Part 55, I discuss this method with my FIRE blogging buddy Fritz Gilbert (Retirement Manifesto). Just like actively managed funds have trouble beating their benchmarks, shifting money around in buckets will not miraculously help you time the market. In the best possible case, a bucket strategy will be hit-or-miss. In the worst possible case, you underperform a passive asset allocation because of commissions and investment fees.

Can leverage raise your sustainable withdrawal rate?

How about using a margin loan to fund your retirement to avoid liquidating assets at an inopportune time? Part 49 deals with that. Part 52 goes into more detail and looks at how much we can improve the results when we carefully time when to use leverage, i.e., when to fund retirement out of the margin loan and when to use withdrawals from the portfolio. The risk of using a margin loan is that if market performance is bad enough, you might face a margin call if you funded too much of your retirement budget with the loan. Besides, with interest rates rising again since 2022, I’d probably stay away from margin loans for now.

How to account for taxes in safe withdrawal rate calculations

I haven’t written much about taxes until Part 35. It’s about planning your asset location (as opposed to asset allocation), i.e., what assets belong in what account types: taxable brokerage accounts vs. tax-free accounts (Roth IRAs, Health Savings Accounts) vs. tax-deferred retirement accounts (IRAs, 401(k), etc.). And in Part 44, I write about some general tax optimization principles. Part 45 has a case study and an Excel Toolkit I use for tax planning and optimization.

Special Topics

The impact of inflation on retirement withdrawals

How much of a difference would it make if you don’t have a perfectly flat withdrawal profile over time? Maybe skip the inflation adjustments?I look that at in Part 5 – Cost-of-Living Adjustments (COLA). Related to that, back in 2020, we found ourselves in a low-inflation environment. Due to the lower predicted COLA in that case, can we increase our sustainable withdrawal rate? Probably not, at least not by much. See Part 41! The opposite is true as well! In 2021 and early 2022, CPI inflation spiked. That doesn’t necessarily mean that we have to lower our SWR. See Part 51.

Homeownership and mortgages

Mortgages and (early) retirement don’t mix! In Part 21 I go through my rationale for paying off the mortgage before retirement: Having a fixed, inflexible payment like a mortgage is poison from a Sequence Risk perspective, especially with today’s high interest rates. That said, if you were lucky enough to lock in a 30-year mortgage interest rate at 3%, you likely want to keep that mortgage for now.

Accounting for homeownership in general: please see Part 57. A persistent myth in the personal finance community circulates, falsely claiming that homeowners enjoy a much higher withdrawal rate because they face less housing inflation than renters. I show that homeownership has a small positive effect on the sustainable withdrawal rate. But the effect is quantitatively negligible.

How does Rental Real Estate fit into early retirement planning? How do we model safe withdrawal and safe consumption rates with a real estate portfolio? See Part 36 of the Series!

Can a high dividend yield generate better investment outcomes?

Part 29, Part 30, andPart 31all deal with the widely held misconception that we can easily save the 4% Rule if we were toincrease the dividend yield to a level close enough to your 4% annual withdrawal rate. Live off your dividend income, avoid ever selling your principal at depressed valuations, and shield your annual withdrawal amounts from Sequence Risk, right? It certainly sounds intuitive and I was intrigued enough to research this option and hoped it could lower Sequence Risk. People in the FIRE community call it “Yield Shield,” but that label is extremely deceptive because it doesn’t work reliably. It would have backfired really badly during the 2007-2009 bear market and again in 2020. Instead of shielding yourself from the downturn, you would have aggravated the Sequence Risk. Sticking to a balanced portfolio with equity and bond index funds is best.

Related to the “Yield Shield,” in Part 40, I look at how your retirement budget would have looked if we had lived off the dividends of an S&P 500 equity portfolio without ever touching the principal. This will not be a viable hedge against Sequence Risk for most retirees. Dividends are often stagnant or even cut during market downturns.

Adding gold, commodities, etc., and studying various model portfolios

How about exotic asset allocation strategies? In Part 34, I write about the impact of adding Gold. And it turns out that the safe-haven asset indeed alleviates Sequence Risk, precisely during the bad historical bear markets (1929, the 1970s). That said, some of the other heavily hyped, “sexy” asset allocation flavors like the “Permanent Portfolio,” “Risk Parity/All-Weather Portfolio,” and “Golden Butterfly Portfolio” not don’t add value but sometimes even lower your sustainable withdrawal rate.

The Effect of the Rebalancing Frequency on Safe Withdrawal Rates

A critical practical concern for retirees: How often do you want to rebalance your portfolio? Can the rebalance strategy and frequency compound or alleviate Sequence Risk? See Part 39. My findings indicate that investment outcomes can differ slightly. On average, there may be an advantage in rebalancing only every 3-6 months, but it’s not guaranteed, and the average benefit is in the range of only 0.01%.

Summary and Suggestions

Withdrawing money from your nest egg is much more complicated than the “simple math” and “simple path” to accumulating assets. I can’t change that. But if you spend 10-15 years saving diligently to invest six-figure or even seven-figure sums, it may also be a wise “investment” to spend a few hours to familiarize yourself with the challenges of withdrawal strategies.Depending on where you are in your FIRE journey and your personal preferences, I’d suggest proceeding as follows:

  • A new reader, not even close to early retirement, just looking around: Start with Part 26 and Part 27. Don’t sweat any technical and more detailed posts linked there. But if something sparks your interest, check that out, too!
  • For the math geeks: Sure, add Part 1 (simulation details) and all the nitty-gritty details on Sequence Risk (Part 14, Part 15). And the mathematical appendix with formulas (Part 8) for the math pros!
  • Getting closer to retirement: You probably want to start looking into performing your own personal safe withdrawal simulations. I’d suggest you familiarize yourself with the Google Sheet and the two posts that explain how to use it (Part 7 and Part 28).Probably also check out Part 4 and Part 17 on how to treat supplemental cash flows. And getting closer to retirement in this day and age, you can’t escape the reality of expensive equity valuations, so you probably want to convince yourself that PE ratios (and CAPE ratios) have an impact on sustainable withdrawal rates: Part 3!
  • I’d also urge every reader close to a “Lean-FIRE” retirement to check out some of thesimulations in Part 23, Part 24, and/or Part 25.Can you stomach a multi-year (maybe even 20-year!) drought period with lower withdrawals? Lower than your already “bargain-basem*nt budget?” If you don’t mind cutting your already optimized budget and/or doing a side hustle for that long then, sure, go ahead. But if you don’t, then maybe plan for a bit of a cushion, and don’t pull the plug the minute you reach 25x annual expenses!
  • For more adventurous, hands-on, and not 100% passive investors: Make sure you check out the dynamic asset allocation posts: Glidepaths (Part 19 and Part 20) and/or Prime Harvesting (Part 13).

Update 11/15/2021: if you like to navigate across the different parts of the series, there is an easy way:

  • is this landing page
  • will get you part XY or the series, for example, the “swr01” suffix for part 1, “swr02” for part 2, etc.
  • Notice that parts 1-9 need to be entered as two digits with a “0” in front and the suffix, i.e., the “/swr” part is case sensitive, all lower letters!
