The league sets the starting point. Promotion 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. Brühl have 5 in 10 this season (2 of 5 at home), Grand-Saconnex 7 in 10 (3 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 63% and 69%.
Last season still counts, briefly. With 10 and 10 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 69% and 70%.
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 69%.
Head to head. These sides have met 4 times in three years, producing over 2.5 goals in 75%. 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 70%.
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 61%, from expected goals of 2.02 for Brühl and 1.12 for Grand-Saconnex. Folding in 30% of that view gives 67%.
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.
