How profit is calculated: each tip carries a simulated $10 stake. Games with bookmaker odds (The Odds API) settle at the real decimal price for the tipped team; games without an odds snapshot settle at a representative $1.90; drawn games refund the stake. Odds coverage shows the share of tips settled at real prices.

Current SeasonWeighted Tip Model
v72The Weighted Tip model combines all 5 ML model predictions using a linear regression trained on 76 historical games. Each model contributes a margin weight (influence on score margin) and a confidence weight (influence on confidence). The current model (v72) has R² = 0.441 with intercept -2.24. Most influential models: elo rating diff, form wins diff, home advantage home constant. The model is retrained weekly with updated coefficients.
Each model contributes a margin weight (× its predicted margin toward home) and a confidence weight. Models with larger absolute weights have more influence on the final tip.
Margin Weights
Active Boosted Model (XGBoost)
v58The Boosted Tip model is a gradient-boosted tree ensemble (XGBoost) trained on 76 historical games to predict the home-team-signed margin from the same model predictions the Weighted Tip model uses. The current model (v58) reaches R² = 0.853 with MAE = 8.3 points and is retrained weekly. Feature importances below are mean |SHAP| values — how much each model's margin and confidence signal moves the prediction, with elo rating diff, value win rate diff, form wins diff the most influential.
