A few hundred = ITM.
ROI takes a huge sample to have an accurate idea. Course you don't actually need a huge sample to know roughly where you are at (or for someone else to judge this for you).

No-one was saying that your ROI is accurate, just that your results are good enough to take a gamble that you are a winning player at the $22s /images/graemlins/wink.gif

"I simplified this to counting how often the observed ROI is +/-5% away from the true ROI:

100 games: ~23%
300 games: ~40%
1000 games: ~66%
2000 games: ~82% "

I guess a few thousand was right /images/graemlins/wink.gif
