Every prop on WagerLens comes with a confidence label: Strong, Lean, or Risky. These labels tell you how much historical evidence supports a given trend, so you can quickly separate high-conviction plays from coin flips.
A confidence score isn't a prediction. It's a measure of how consistently a trend has performed based on real data. Think of it as a filter. It helps you spend your time on the props that actually have something behind them.
What goes into the score
Behind each label is a composite score built from several weighted signals:
- Expected value (EV) — Does this prop have a positive expected return based on the odds? This carries the most weight of any single input.
- Sample reliability — Bayesian adjustment that accounts for small sample sizes. A 5-game hot streak gets less credit than a 20-game trend.
- Market consensus — How closely different sportsbooks agree on the line. Tight consensus suggests the market is efficient; wide disagreement can signal opportunity.
- Hit rate composite — Weighted average across recent game windows (last 3, 5, 7, and 10 games). More recent performance carries more weight.
- Consistency — How stable the player's performance has been. A guy who hits 8/10 games is more trustworthy than one who hits 8/10 but with wild swings.
- Context — Sport-specific adjustments, plus injury status and games since returning.
You don't need to think about these individually. The score combines them, and the label gives you the bottom line.
Notice what sits at the top of that list. EV carries more weight than hit rate, and that's deliberate. A prop that hits constantly at a terrible price is still a bad bet. A score driven mainly by hit rate would happily tell you otherwise.
The three confidence tiers
Strong (75+)
The trend has consistent historical backing across a solid sample size. These are your highest-conviction props, the ones where multiple signals agree.
When you see a Strong label, the data is telling you this trend has held up. It's still worth checking recent news and injury reports, but the foundation is there.
Lean (55–74)
There's supporting evidence, but it's not overwhelming. Maybe the sample is smaller, or the recent hit rate is good but inconsistent. These are worth a look, especially when you have additional context that supports the play.
A Lean prop paired with a favorable matchup or a line you like can still be a solid bet. But on its own, it's not a high-confidence signal.
Risky (below 55)
The data doesn't support this trend. Small samples, inconsistent results, or negative expected value. These props might still hit, because anything can happen in a single game. But the historical evidence isn't on your side.
Unless you have a strong independent reason to bet a Risky prop, skip it. There are usually better options on the board.
How to use confidence tiers in practice
- Start with Strong props. Focus your research time on the top tier and you'll find better opportunities faster. Labels show up on the dashboard's top-props section, on player and team pages, and in the prop detail view.
- Use Lean as a second look. If a Lean prop lines up with something you've already researched (a matchup edge, a recent role change, a coaching adjustment), it can be worth adding to your card.
- Don't bet Risky out of boredom. The biggest bankroll killer is betting just to have action. If the board is full of Lean and Risky props, that's the market telling you to sit tight.
- Track your results by tier. Over time, you'll see how each bucket actually performs for you. My Bets is how you get that feedback loop without relying on memory.
Common mistakes
- Betting a Risky prop because "it just feels right." The score exists specifically to counter gut-feel bias.
- Ignoring recent news because a prop is labeled Strong. Confidence scores use historical data. If a player just got hurt in warmups, the label doesn't know that yet.
- Sizing up bets just because the confidence is high. Strong doesn't mean certain. Even the best trends lose. Keep your unit sizing consistent.
What confidence scores don't tell you
Confidence is one input, not the whole picture. You still need to factor in:
- Injury reports and lineup changes
- Matchup context (who's guarding who, pace of play)
- Weather for outdoor sports
- Line movement and where the sharp money is going
- Your own bankroll management rules
The best use of confidence scores is as a starting filter. Let the data narrow your focus, then apply your own research to make the final call.
One more thing worth being explicit about: a confidence label describes the evidence, not the outcome. Strong doesn't mean likely to win. It means the historical case is well supported at the price we saw. Those are different claims, and conflating them is how a useful filter turns into a bad habit.
