Premiership · Monday, 3 August 2026. Final score 1–0 (half-time 0–0). Rebuilt from the season as it stood that morning, our rating would have been 54% 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 Celtic at 74%, the draw at 18% and Dundee at 8%, from expected goals of 2.21 and 0.58.
The league sets the starting point. Premiership has produced over 2.5 goals in 52% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Celtic have 0 in 0 this season, Dundee 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 52% and 52%.
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 61% and 55%.
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 57%.
Head to head. These sides have met 10 times in three years, producing over 2.5 goals in 70%. 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 58%.
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 53%, from expected goals of 2.21 for Celtic and 0.58 for Dundee. Folding in 30% of that view gives 56%.
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 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.
