The result model puts Rapperswil at 48%, the draw at 21% and FC Winterthur at 30%, from expected goals of 2.06 and 1.61.
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 2 in 3 this season (1 of 1 at home), FC Winterthur 2 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 63% and 60%.
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 66% and 75%.
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%.
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 71%, from expected goals of 2.06 for Rapperswil and 1.61 for FC Winterthur. Folding in 30% of that view gives 69%.
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.
