For each thing Vesta gives a chance or a number to, what it expected and what happened. A forecast of 30% should come true about 3 times in 10: the closer the two columns, the more its numbers can be taken at their word.
Each kind of match has its own model; each is checked apart.

The current club champion, dc_xg2_cal_pl_pool_com (H01b, H19, H20, H21, H22, H24), has no checked forecast yet: its first ones are checked as their matches are played. When a kick-off moved to another day, the forecast published last before the real kick-off is the one checked; 74 earlier forecasts published under the old date are kept in the log but not checked. 3 matches forecast before kick-off were called off (15 forecasts kept in the log, not checked): Sri Lanka v Djibouti, 2026-10-03, cancelled (ESPN status (automatic), ESPN event 401912238 STATUS_CANCELED); Tunisia v Mali, 2026-10-03, cancelled (ESPN status (automatic), ESPN event 401916228 STATUS_CANCELED); Bolivia v Gambia, 2026-10-04, cancelled (ESPN status (automatic), ESPN event 401925303 STATUS_CANCELED).

The live 1X2 is a model estimate: on past seasons it beats the forecast before kick-off at every minute, but its calibration is not yet within our tolerance at half-time and near the end. How Vesta works ›
Brier score: the average, over every outcome Vesta gave a chance to, of the squared gap between that chance and what happened (1 if it happened, 0 if not). 0 is perfect; for the match result, giving each of the three outcomes a third scores 0.222. The charts show only the chance bands with 20 forecasts or more.
