Re: Diff b/t ROI + ROR???
For a typical sng paying three spots, SD is calculated as follows:
SD=SQRT((Probability of 1st)(net profit for 1st)+(Probability of 2nd)(net profit for 2nd)+(probability of 3rd)(net profit for 3rd)+(probability of finishing out of the money)(net loss)+(avg profit/tourney^2))
