Re: \"How many hands do I need to play...\" definitive answer
To get within 10% of actual win rate you need a sample of about 40,000 hours. To get an estimate to within 20%, you need only 10,000 hours. I am assuming that SD/EV=10 here. If you want to figure it out using your own stats, the 95% confidence formula is
n=((196*SD)/(EV*r))^2
where n=no. of hands needed to estimate EV per hour (=win rate) to within r% of the actual EV. ^2 means "squared".
