Questions about the ev calculator
What does +EV mean?
Positive expected value means a bet should make money on average over many repeats. EV per unit staked = (win probability × decimal odds) − 1.
How do I estimate the win probability?
From your own model, statistics such as expected goals, or prices at sharp bookmakers. The result is only as good as your estimate, so be honest about how sure you are.
