Re: BB/100 variations question !
Use this formula :
xbar +- z*(s.d)/sqrt(number of trails)
xbar is your sample win rate through the number of hands you're interested in .
z is the level of confidence you'd like . Typically , we'd like z=2 or about a 95% confidence level .
s.d/sqrt(number of trials) is your sample standard deviation. Each trail consists of 100 hands , so 50k hands would be equivalent to 500 trials .
