Monthly Brier from each match's pre-match prediction (walk-forward, no hindsight). A flat line below the 0.25 coin-flip mark means the model stays calibrated month after month — no drift.
Stable numbers across windows mean the model isn't drifting. Sample size shown so equal rates aren't misread.
Predicted vs actual win rate per band — close numbers mean the probabilities are honest.
On the diagonal = honest. Above it = the model was too cautious, below = overconfident.
