Bankroll considerations based upon estimated edge and Kelly criterion?

Thanks for the helpful response.

To give you a rough feel of fluctuations and bankroll requirements, a typical win rate for a good player in a casino game is in the ballpark of one big bet per hour (e.g., $8/hr in a 4/8 game) and a typical standard deviation is roughly ten big bets per hour (e.g., $80/hr in the same 4/8 game).

I think this info can be turned into some meaningful estimates related to a Kelly-based bankroll; I strongly suspect the 300-500 BB recommendations came from a consideration of the formula.

300*BB allows you to have 10 losing sessions of 2BB's pr hr over 10 8hr sessions and still have 140 BB left.

That's 10 losing sessions at 10/20 totaling 160BB/$3200 and leaving you a bankroll of $2800.00/140BB.

I really don't think it's possible for a good player to average that much of a loss over 10 sessions. Even if it's so, he has over 1/2 his bankroll left.

I'm talking 1 table live poker here.
