Hit rate

Won divided by won and lost. A void, such as a draw on draw no bet, counts in neither. It is always shown beside the mean probability of the same predictions.

Scored version

A prediction can move before kick-off, and every version stays on the record. Only the last version published before kick-off is scored.

Calibration error

The gap between probability and how often it happened in each tenth of probability, averaged with each tenth weighted by its predictions. The Brier score is the mean squared error of every probability.

Slip landing rate

Slips landed divided by slips landed and lost, beside their mean combined probability: the probabilities of their legs multiplied together. A void leg drops out, as bookmakers settle it.
