Also, a kinda dumb question as long as I'm on the subject of ror.

When calc'ing the ror, should I be using ev and std dev for 100 hands, or for one hand?

if it's for one hand, then what should I be doing?

ev = 0.02, of course.

now is std dev 0.15, or is it 1.5? (i.e. should I be using the sqrt of 100 or just dividing it?)
