What are High Confidence Props?

High Confidence Props are betting opportunities that pass multiple quality filters:
  • High Expected Value (EV >10%)
  • Strong recent player form (last 5 games)
  • Favorable matchup based on opponent defense
  • Adequate sample size (20+ games analyzed)
  • No injury concerns
These represent the best betting opportunities identified by Line Gap’s analysis engine.

How Props are Rated

Each prop receives a confidence score based on:

Historical Performance (40%)

  • Player’s hit rate on similar lines
  • Consistency over last 20 games
  • Recent form weighted higher

Advanced Probability Models

Line Gap uses a Dual Probability Model to ensure accuracy:
  1. Current Season Only: Pure performance in the 2024-25 season.
  2. Weighted Multi-Season: A blend of current and previous season data, weighted heavily towards recent performance (2x weight for current season).
This approach handles small sample sizes early in the season while respecting long-term trends.

Injury Impact Analysis

Our engine automatically detects when key teammates are injured and adjusts probabilities accordingly:
  • Usage Boosts: We calculate how a player’s usage rate changes when a specific teammate is out.
  • Impact Score: Probabilities are boosted (e.g., +5%) based on historical data from games played without that teammate.
  • Context: This ensures you don’t miss “next man up” opportunities.

Matchup Analysis (30%)

  • Opponent defensive ranking
  • Historical performance vs this opponent
  • Pace of game factors

Expected Value (20%)

  • Implied probability vs true probability

Context Factors (10%)

What Makes a Prop “High Confidence”?

Must-Have Criteria

Significant edge over sportsbook. Lower EV props won’t qualify regardless of other factors.
Need sufficient data. Rookies or players returning from injury won’t appear until enough games played.
Player must be healthy. Questionable/doubtful status disqualifies props.
Line must be within player’s normal range. Extremely high/low lines have higher variance.

Bonus Factors

Props get extra points for:
  • Favorable opponent matchup
  • Hot recent form (last 5 games)
  • Home game advantage
  • Fresh legs (rest days)
  • Consistent performance (low variance)

Common Questions

Q: Why don’t I see my favorite player? Not every player appears in High Confidence. They must meet all quality thresholds. Check the main Dashboard for more props. Q: Should I bet all High Confidence props? No. Even elite confidence props can lose. Diversify across 3-5 props and manage your bankroll properly. Q: How often are props updated? High Confidence props refresh every time odds are fetched (every 5 minutes via cron jobs). Q: Can I filter by specific prop types? Yes! Use the prop type filter to show only Points, Assists, Rebounds, etc.

Performance Tracking

  • Hit Rate: Percentage of props that won
  • Average EV: Mean expected value
  • Actual ROI: Real money profit/loss
  • By Confidence Tier: Breakdown of performance by level
