Eliteserien · Sunday, 15 March 2026. Final score 2–0 (half-time 0–0). Rebuilt from the season as it stood that morning, our rating would have been 58% 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 KFUM Oslo at 54%, the draw at 23% and Start at 23%, from expected goals of 1.97 and 1.22.
The league sets the starting point. Eliteserien has produced over 2.5 goals in 62% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. KFUM Oslo have 0 in 0 this season, Start 0 in 0. 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 62% and 62%.
Last season still counts, briefly. With 0 and 0 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 57% and 62%.
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 60%.
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 62%, from expected goals of 1.97 for KFUM Oslo and 1.22 for Start. Folding in 30% of that view gives 60%.
Season opener. One of these sides has not played a league game yet. Openers run about 2.5 points under their league's norm, measured across 2,727 of them, so the rating is docked to 58%.
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.
