Ekstraklasa · Friday, 9 October 2026. Final score 1–4 (half-time 1–1). Before kick-off we rated it 56% over 2.5 goals — the match finished with 5, so that call landed. That rating was frozen into a version-controlled ledger before the game and has not been touched since.

The result model puts Raków Częstochowa at 41%, the draw at 25% and GKS Katowice at 34%, from expected goals of 1.57 and 1.42.
The league sets the starting point. Ekstraklasa has produced over 2.5 goals in 53% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Raków Częstochowa have 8 in 9 this season (5 of 5 at home), GKS Katowice 7 in 8 (4 of 5 away). Those records are pulled toward the league rate with the weight of about 24 matches — enough that two or three unusual games cannot swing a rating — giving 63% and 62%.
Last season still counts, briefly. With 9 and 8 games played this season, last season's rates are still blended in and fade out entirely by game 40 — the point at which our testing showed they stop adding accuracy. A single season is part luck, so each club's record is first pulled toward the league average by 34 games' weight. That moves the two figures to 53% and 54%.
The mix. Weighted 40% home side, 40% away side and 20% league — the split that beat every alternative across 30,582 matches of testing — that gives 53%.
Head to head. These sides have met 4 times in three years, producing over 2.5 goals in 25%. That nudges the number 5% of the way toward the head-to-head pattern — deliberately small, because fixtures change more than reputations do — landing on 52%.
Goal expectation. Separately a Poisson model built from attack and defence strength — using real expected-goals data where the league has it — puts this match at 57%, from expected goals of 1.57 for Raków Częstochowa and 1.42 for GKS Katowice. Folding in 30% of that view gives 54%.
This breakdown is generated from the same inputs the rating uses, so it cannot describe a calculation we did not perform. The full model is set out in the methodology.
