Question for stt experts

probably been asked lots before but over how many games should you be able to determine your expected roi. I'm thinking that if my roi over 1000 games is 20% then over the next 1000 I can expect to hit 20% +/- say 4%, is 1000 enough of a sample size to make this assumption

I havent done the math but I would say yes, 1000 is more then enough of a sample size to get a +-4% confidence level. Just off the top of my head.
