Performance questions

What does this performance page show?

A public record of published forecasts after kick-off: favourite-correct, exact score, Over 2.5 and BTTS, plus walk-forward log loss on the frozen sample.

Why is live accuracy different from the 909-match number?

A single round is a small sample. Several draws against favourites can move live accuracy a long way. Log loss on the frozen set is the number we treat as quality.

Can I filter by league and round?

Yes. Each league and each scored round has its own URL, so the table, title and stats are specific to that slice.
