Model context
BN NFL V4 preserves the chronologically validated V3.4 win-probability model — opponent-adjusted EPA and success rate, pressure, explosive plays, third downs, red zone, QB intelligence, Elo and player-aware injury availability — and adds a probability-consistent score layer so the projected score and favored team no longer contradict the win probability. Prediction ranges use chronological out-of-sample empirical score residuals. Weather remains part of Matchup Intelligence but is not used in the current prediction calculation. New prediction snapshots are timestamped rather than overwriting earlier forecasts.
