Model Card

Training-only average margin baseline. Another cheap sanity check for whether a richer team model adds signal beyond raw per-game margin.

Validation on this page uses stored season-level full-fit rows plus strict weekly rolling holdouts. Rolling ranks are based on average weekly log loss in the selected league/season. Current scope: All Games. All scored games in the selected league and season. AP Poll is excluded here.

Full Fit AUC 0.784 (#7) · 5361 games
7-Day Holdout Log Loss 0.671 (#13) · 13 games
Rolling Avg Log Loss 0.620 (#11) · 22 windows
Window Wins 0 · 68.0% rolling accuracy

Full-fit AUC is only available where the older stored-rating batch produced that model for the selected scope. Recency and ensemble families can still have valid 7-day and rolling holdout results even when the full-fit columns are blank.
