Yes, Jim's annuitization of BRK posts were amongst my favorites. Would be great if you or Jim could share those posts you saved from the old MF boards. He had some superb data with year by year IV, Market price and comfortable draw down guidance which I believe it was as high as 8% on average without losing the initial $1M investment. I recall only a few years where you could only withdraw under 4% based on BRK business performance which seemed around the GFC. I am waiting on my initial draw down until we approach that P/peak BV of 1.55 or so like last Spring. 1% per quarter seems reasonable but I like the thought of timing the sell when closer to its IV. I quoted this from Jim from a previous post:

''So long as a share of Berkshire keeps rising in value at over (say) inflation+6%/year, then one can cash out that much on average without ever reducing the value of the portfolio.
The method proposed automatically cuts the payouts if/when business results falter, though with a
slight lag, so any slowdown in the business becomes a slowdown in withdrawals, not a risk of eating into the capital''
