I haven't done this to much on the forums as I don't believe anyone really cares...units won/lost seems to dominate. I have noticed that rolltide (a capper I respect) has chimed in with ROI in acouple different threads. I will add ROI to my season thread and correct me if I am wrong, it's figured like this. $1,000 dollars risked and you have a net winnings of $200 that is a 20% ROI, right.
