An interesting article that generated some new thinking for me. Basically, more people retire in a bull market (because they hit their number), and since bad markets follow good markets (unless this time is different ), the 4% rule is not as conservative when looking at a 60 year time horizon.

"Using the MMM Simple Math method, you’ll mostly retire during a bull market, and often during the last part of the bull market, right before the peak and the next bear market!"
As the author summarizes, it's not a huge difference, but it does highlight that for some cohorts the 4% rule is not overly conservative.
