Model vs market

Each dot is a runner: model probability across, market-implied probability up. Dots on the dashed line mean the two agreed; the gold ring is the actual winner.

Ratings are statistical estimates for analysis, not betting advice — the backtest shows no profitable edge against the Hong Kong win market. How the model works →
