You guys are little off about winrates. For a player who has grinded up to the level of 100nl, it's almost impossible to think he could run more than 6ptBB/100 in the long run if that. But for one of the best 600nl regs and a guy taking a shot at 1k nl I thinks its more than plausible that Sauce could run 10+ptBB/100 in the long run.

But even then, you can expect to have a 10 buy in swing at one point in 100k hands so you at least need 12 buy ins id think. But still this is all theoretical stuff that will never apply to anyone. 20buyins+ is a good rule.
