Model vs market

Backtest 2025 to Oct 2026 (trained from 2023), 304 games, 1X2 ranked probability score (lower is better): model v2 0.2077 vs old model 0.2335 vs closing line 0.2008. Added Oct 2026: team goal ratings from all domestic leagues plus a cross-league strength offset fitted on European/cup results (ESPN). v1 = home/draw/away base rates. The model alone trails the closing DraftKings line (0.2008), so the published projection is 85% market: 1X2 RPS 0.2004 vs market 0.2008, O/U Brier 0.2428 vs 0.2429.
