An example
You bet the Packers at +120. By kickoff they are +105. You beat the closing line. Do that again and again and your results tend to follow.
Why it beats win rate
Wins and losses take hundreds of bets to mean anything. CLV shows up after a few dozen, because it measures the price you got, not the coin flip of the game.
Check yours
Every bet you log in My bets records your price and the closing price, and shows your average CLV. Our public leaderboard ranks members by it.
