What a hit rate is
A player prop hit rate is simply the share of games in which a player finished over (or under) a given line — say, 20.5 points or 6.5 assists. It is the most intuitive number in prop research: count the games above the line, divide by the games played, and you have a percentage.
It is genuinely useful because it is grounded in what actually happened rather than in a narrative. But a raw hit rate is a starting point, not a verdict, and treating it as a verdict is how bettors talk themselves into bad tickets.
Convert the odds to a probability first
Before you judge any prop, translate the offered odds into an implied probability — the percentage chance the price is quietly assuming. Odds and probability are two views of the same thing, and comparing your own read against the implied number is the whole game.
One catch: the posted odds bake in the sportsbook's margin (the vig), so the implied probability adds up to more than 100% across both sides and overstates the true chance. Removing the vig gives you a fair number to bet against. A prop is only worth playing when your estimate of the real probability clears that de-vigged break-even line.
Context beats the headline number
A 70% season-long hit rate can hide a player who cleared the line easily early, then had the line raised. Slice the sample the way the matchup actually looks: recent form (last 10 vs the full season), home vs away, and performance in wins vs losses. A player whose production collapses in losses is a very different bet when his team is a big underdog.
Sample size matters too. A hit rate over five games tells you very little; the same rate over 30 games is far more trustworthy. When a recent stretch disagrees sharply with the longer sample, that is a signal to dig in, not to pick whichever number supports the bet you already wanted.
A repeatable process
Put it together into a routine. Convert the odds to an implied probability and strip the vig. Pull the player's game log and compute the hit rate at the exact line on offer. Re-check that rate in the relevant context — opponent, location, and game script. Only bet when your evidence-based probability comfortably beats the fair price, and size the bet to reflect how confident you actually are.
On any player page here, the frequency tool does the first pass for you: set a stat and threshold, and it returns the hit rate with win/loss splits plus a fair-odds figure you can hold up against the sportsbook's line.
