Superettan · Monday, 25 May 2026. Final score 2–0 (half-time 2–0). Rebuilt from the season as it stood that morning, our rating would have been 60% for over 2.5 goals. This match is older than our frozen ratings ledger, which keeps 30 days, so that figure is a reconstruction from pre-match data rather than a number we published at the time — a distinction worth making, because only the frozen ones prove what we actually said beforehand.

The result model puts IFK Norrkoping at 54%, the draw at 21% and Osters IF at 25%, from expected goals of 2.13 and 1.4.
The league sets the starting point. Superettan has produced over 2.5 goals in 56% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. IFK Norrkoping have 4 in 8 this season (2 of 3 at home), Osters IF 5 in 8 (4 of 4 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 55% and 58%.
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 56%.
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 68%, from expected goals of 2.13 for IFK Norrkoping and 1.4 for Osters IF. Folding in 30% of that view gives 60%.
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.
