Model vs market
Gap: -0.1 margin, -0.1 total. The projection shown above blends the model with this line.
Backtest 2023-24 to 2025-26, 3,692 games, win-probability Brier (lower is better): model v2 0.2078 vs old model 0.2120. No free archive of NBA closing lines, so we can't benchmark against the market yet. Game totals also use a possession model (shot mix, shooting and pace from team box lines), which cut total-points error by 0.17 pts/game in every test season; it didn't improve win probability, so that stays on v2.
