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 6 in 10 this season (4 of 5 at home), Stade Nyonnais 8 in 10 (4 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 61% and 67%.
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 68% and 56%.
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%.
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 65%, from expected goals of 2.77 for FC Winterthur and 0.55 for Stade Nyonnais. Folding in 30% of that view gives 63%.
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.
