How it works This FBS-specific model blends 308 current-season games with 674 games from 1920, 1919, 1918. Current-season influence is 100% for the rating relationship, 24% for home-field advantage, and 38% for the error range. Before week-eight recalibration, probabilities are limited to 5–95% to reflect early-season uncertainty.
