Profit Factor in Sportsbetting?

[Jan Richter]

Hey, Guys! In trading one of the possibilities to judge a "System" is to calculate the Profit Factor. (Gross Win / Gross Loss). For example i make 500 bets $100 each and win 55% So it would be:
(275*95=26.125) / (225*100=22.500) = 1,16 Profit Factor. Do you guys have anything similar to that? What would be a "good" and what a "realistic" number?

All you need is average win rate * average odds. E.g. 0.55*2 = 1,1 = 10% roi, which is realistic, 15% is pro, 20% is awesome.

I like where your heads at. I will settle w the 15%.
