The result model puts FC Winterthur at 55%, the draw at 21% and Stade Lausanne-Ouchy at 24%, from expected goals of 2.02 and 1.28.
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. FC Winterthur have 2 in 3 this season (2 of 2 at home), Stade Lausanne-Ouchy 0 in 3 (0 of 1 away). Those records are pulled toward the league rate with the weight of about 32 matches — enough that two or three unusual games cannot swing a rating — giving 64% and 55%.
Last season still counts, briefly. With 3 and 3 games played this season, last season's rates are still blended in and fade out entirely by game 14 — the point at which our testing showed they stop adding accuracy. That moves the two figures to 76% 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 67%.
Head to head. These sides have met 3 times in three years, producing over 2.5 goals in 67%. That nudges the number 10% 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 64%, from expected goals of 2.02 for FC Winterthur and 1.28 for Stade Lausanne-Ouchy. Folding in 30% of that view gives 66%.
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.
