Super League · Saturday, 19 September 2026. Final score 1–1 (half-time 1–1). Rebuilt from the season as it stood that morning, our rating would have been 65% 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 FC Sion at 64%, the draw at 20% and FC Zurich at 15%, from expected goals of 2.16 and 0.95.
The league sets the starting point. Super League has produced over 2.5 goals in 68% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. FC Sion have 8 in 8 this season (4 of 4 at home), FC Zurich 8 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 76% and 76%.
Last season still counts, briefly. With 8 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 61% and 73%.
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 67%.
Head to head. These sides have met 7 times in three years, producing over 2.5 goals in 71%. 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 67%.
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 60%, from expected goals of 2.16 for FC Sion and 0.95 for FC Zurich. Folding in 30% of that view gives 65%.
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.
