Sorry,

what I meant to say was assuming ROT = Profit what is the acceptable strike rate.

A long shot system that has 1 bet a day gets very annoying when you haven't won in 3 weeks but if you are betting 50 bets a day then you will usually hit 1 or 2 every day (or second day).

Again this is all assuming the method you use returns a profit.

Good Luck.
