Experiment 02 / What the extra statistics add

More information.
A better forecast?

Test prior-game EPA and yards per play against a score-only correction on the same 784 historical games. Correction models train on 2023; probabilities are calibrated in 2024; this comparison scores the 2025 season.

Full historical test / Primary comparison

No clear gain from the extra features.

Score + efficiency: 13.34 points of margin error. Score-only correction: 13.36. The difference is -0.018 points; the approximate 95% week-block range is -0.182 to 0.155.

This is an exploratory, retrospective comparison. Settings were recorded after the historical season and after the original weekly benchmark was known. Source corrections and publication delays are not reconstructed. Current forecasts and prospective ledger records are unchanged.

2023 / Learn the correction770 games

Fit both residual models and their feature scaling. Freeze those coefficients for later seasons.

2024 / Calibrate787 games

Fit a separate probability curve and nominal 80% margin range for each model.

2025 / Evaluate784 games

Compare the same matchups. Earlier results update later weekly score fits and feature inputs.

Where did the predictions change?

Margin change compares score + efficiency with the score-only correction. All tables use the same selected games. Monthly bars keep program and change filters and let you select a month; the full-test uncertainty range above is fixed.

Method / What this test can establish

More fields need stronger evidence.

The score-only correction and efficiency correction use ridge regression with penalty 100, a free intercept, and means and standard deviations learned only from 2023. Both predict the original weekly model’s margin error. The efficiency model adds four home-minus-away gaps: offensive EPA, EPA allowed, offensive yards and yards allowed, all per play.

Each weekly input pools paired, scored FBS-versus-FBS games from the current and preceding season whose kickoff is before Sunday 00:00 UTC, 24 hours before the Monday bucket. Prior-season totals receive weight 0.5. Each team rate is shrunk toward that cutoff’s pooled league rate with 300 equivalent plays. A team with no usable history receives the league rate. 0 of the test games needed that fallback.

The feature archive contains 3,124 paired advanced games and 65 dated states. Missing or incomplete advanced pairs do not enter those rate pools. The score fits still use their full eligible score samples. The 2025 evaluation retains the original weekly benchmark’s 784 games and its 24 exclusions for teams outside the frozen field.

Single-season residual training, unadjusted efficiency inputs, repeated teams, later source corrections and an already-observed historical test season limit this result. The 5,000-resample week-block interval retains whole weeks and recomputes game-weighted error; teams recur across weeks, so it does not remove all dependence. No live betting advantage or new production model is claimed.
