How to read this
Units are 1-unit-normalised and sized by Kelly criterion at pick time, so units and win rate move independently — a sub-50% win rate can still be profitable on longer prices, and a high win rate on heavy favourites can lose units. ROI is units won over units staked.
Individual game pages are retired 90 days after the event; this page is the permanent record of what the model actually did.
