Superettan · Sunday, 19 July 2026. Final score 3–0 (half-time 2–0). Rebuilt from the season as it stood that morning, our rating would have been 53% 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 57%, the draw at 24% and Sandviken at 19%, from expected goals of 1.78 and 0.92.
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 5 in 14 this season (2 of 6 at home), Sandviken 9 in 14 (4 of 6 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 49% and 59%.
Last season still counts, briefly. With 14 and 14 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 49% 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 54%.
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 51%, from expected goals of 1.78 for IFK Norrkoping and 0.92 for Sandviken. Folding in 30% of that view gives 53%.
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.
