Kelly Criterion, ROI, and Staking

[Luxoris]

meh. You can still get an average ROI and standard deviation (both factoring in the staking deal) for the players results which should come close enough for a KC calculation. The answer? A boatload of buyins for anything approaching even a 1 standard deviation confidence in not dropping your player before he hits a bit enough cash to turn positive.

Small stakes for a lot of frequent tourney players is probably going to be far more satisfactory than just backing a couple of horses in large buyins.
