Probability calibration
Observed win rate should approach the average predicted probability as sample sizes grow.
| Probability | Games | Predicted | Observed | Gap | Brier |
|---|---|---|---|---|---|
| 0–9% | 1 | 8.5% | 0.0% | -8.5 | 0.007 |
| 10–19% | 32 | 16.7% | 18.8% | +2.0 | 0.160 |

Performance by prediction confidence
Newer snapshots use historical calibration and comparable sample size. Legacy snapshots fall back to rating-evidence confidence.
| Confidence | Games | Winner accuracy | Average margin error |
|---|---|---|---|
| High | 252 | 55.6% | 22.8 points |
| Medium | 21 | 76.2% | 21.5 points |
| Low | 434 | 61.3% | 22.5 points |
Performance by risk indicator
A game may appear in more than one group because indicators describe different kinds of uncertainty.
| Indicator | Games | Winner accuracy | Average margin error |
|---|---|---|---|
| Limited Data | 706 | 59.6% | 22.6 points |
| Close Game | 535 | 56.8% | 22.8 points |
| Upset Possible | 505 | 56.0% | 22.4 points |
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.
