Game-by-game audit
Each completed game updates this team's rating using opponent strength, home-field advantage, and how the result compared to expectation. For every game below you can see the rating at kickoff, the opponent's rating, the model's expected margin, the actual scoreboard margin, the gap between those two, and the exact rating points gained or lost. Ratings and game-audit tables for each published week are linked above that week's results.
