Performance by risk indicator

A game may appear in more than one group because indicators describe different kinds of uncertainty.

Largest misses

The largest margin errors in this selection. A miss is a model result to learn from, not automatically a data error.

How to interpret these numbers

Winner accuracy shows whether OSPR favored the team that won. Average margin error shows how far the projected point margin was from the final margin.

Brier score measures probability quality from 0 to 1; lower is better. Calibration compares predicted win probabilities with observed outcomes.

Small groups can swing sharply, so every percentage is shown with its evaluated game count.

Injuries, roster changes, weather, and information not reflected in recorded results may affect individual games.
