How accurate is the rating?
Before every rated match, the rating implies a win probability. We keep those predictions and score them against what actually happened — across 4,864 decided matches. A well-calibrated rating means our 65% picks win about 65% of the time. Nothing here retunes the model; it only reports on it.
| Predicted | Observed | Matches |
|---|---|---|
| 7% | 17% | 142 |
| 16% | 31% | 244 |
| 25% | 36% | 344 |
| 35% | 42% | 505 |
| 46% | 47% | 821 |
| 54% | 57% | 1153 |
| 64% | 63% | 658 |
| 75% | 69% | 502 |
| 85% | 80% | 335 |
| 93% | 87% | 160 |
Brier score
0.228
Mean squared error of the prediction. Lower is better; 0.25 is what always guessing 50/50 would score.
Calibration error
0.048
Average gap between what we predicted and what happened, weighted by how many matches sit in each bucket. 0 is perfect.
Log loss
0.650
Penalises confident-and-wrong predictions much harder than cautious ones.
Measured over the matches the rating engine actually rates. Predicted 52.2% on average and observed 54.4% — those two should sit close together for an unbiased model.
How settled are the numbers?
A Glicko rating is an estimate with an error bar, not a fact. That error bar is the rating deviation — the ± 68 printed next to every rating on the site. It narrows as a team plays and widens again while a team sits idle, so a wide band means “we are not sure yet”, never “this team got worse”.

A further 3352 teams are still provisional — the engine flags a rating that way while its uncertainty is above 200 or it has played fewer than 5 rated matches. Those numbers exist, but they have not converged, so they are kept out of the main ladder and out of every record on this page.

Records cover the public Glicko engine's own rating history, which begins 2 Jan 2026. Ratings the engine still flags provisional are excluded, so a wilder number from a team that had not converged will not appear here. “This season” is measured from 1 Jan 2026.
The full rating methodology — the Glicko-2 algorithm, decay, data sources, and known limitations — lives on the methodology page.
