Model probability (from backtest calibration under your live weights) vs the book's implied probability. Direct book feeds are blocked, so enter the odds you see — favorable (+EV) props get flagged, and you can send a favorable one straight to a prediction.

Replay historical lineups with point-in-time stats, score every hitter under your settings, and compare against what actually happened. Optimize sweeps weight combinations to find the settings with the best backtested hit rate. First run for a new date range fetches data and may take a minute; results are cached after.

Tune these weights and thresholds to shape how matchups are scored. Weights (ERA / OPS / Form) should sum to 100.
