Challenge League · Friday, 9 October 2026. Final score 0–3 (half-time 0–1). Before kick-off we rated it 54% over 2.5 goals — the match finished with 3, so that call landed. That rating was frozen into a version-controlled ledger before the game and has not been touched since.

The result model puts Rapperswil at 27%, the draw at 26% and Stade Lausanne-Ouchy at 47%, from expected goals of 1.1 and 1.53.
The league sets the starting point. Challenge League has produced over 2.5 goals in 61% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Rapperswil have 5 in 9 this season (1 of 4 at home), Stade Lausanne-Ouchy 3 in 9 (1 of 5 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 60% and 54%.
Last season still counts, briefly. With 9 and 9 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 63% and 61%.
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 62%.
Head to head. These sides have met 5 times in three years, producing over 2.5 goals in 40%. 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 61%.
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 49%, from expected goals of 1.1 for Rapperswil and 1.53 for Stade Lausanne-Ouchy. Folding in 30% of that view gives 57%.
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.
