How many 11's should I have logged before I know that my ROI is reasonably accurate?

I thought the number was around 200?
Wasn't sure tho...

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

Fine :P
if we must get into technicalities, I did say "similar question"
"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
