Re: Ribbit\'s Edits

really? I remember this came up before and you told me increasing your SD does not massively increase your bankroll requirement (unlike decreasing your winrate). My SD is something like 70ptBB/100 and I don't think this is particularly high-variance, but I would be happy with 60BI for any game I thought I had a noticeable edge in.

I should also say that there is an issue of uncertainty. Your PTO SD numbers should be very close to your "true long run" deviation.
Win rate, however, is very difficult to estimate. If you play at levels where 3 ptBB/100 is very good, it takes a lot of hands to estimate your win rate within 1 ptBB. And by the time you have this many hands, your old data may no longer be valid. If your estimated win rate is 3, a difference of +/- 1 in your win rate would make the difference between needing 30 or 60 buyins.
