    Assume a player has an average buy in of 50 dollars

    Assume that he has logged 3k games

    Assume that his ROI over that sample is 10%

    Assume he plays on a very weak site

    How close is this player to his true roi?

    +/- 2 or 3 percent?

    Or is the sample size not big enough to make an accurate guess and he could just be a donkey running well?

    Almost no chance you are off by 3% over 3k stts.

    If you go to the FAQ in the STT strategy section of 2+2...under 'variance and sample sizes' or something there is a ROI simulator which will basically answer all your questions. You just have to plug in the numbers for your finish distributions and sample size and it will tell you the % chance your actual roi is >X, what your biggest downswing will be in that that number of games on average etc. Its rly good.
