What the model leaned on

Stats that mattered most

Ranked by how much attention the model gave each stat during training. “Validation” checks the stat on games the model did not train on: helped is encouraging, hurt means the stat needs more scrutiny. Attention alone does not prove a stat predicts winners.

Model Trust

Does the model beat the market?

Honest out-of-sample backtest vs closing lines (2012-2021), model retrosheet-game-complexity-reset-travel-2026-shadow-v12. ROI is flat-stake at close, pushes refunded. A model that scores worse than the market (higher Brier) has no defensible edge even when ROI looks positive.

legacy operator override after beating incumbent: retrosheet-game-complexity-reset-travel-2026-shadow-v12 vs retrosheet-game-through-2025-compact-context-v11 on 14374 games (Brier -0.0015, log loss -0.0032).
