The result model puts Cham at 34%, the draw at 22% and Zürich II at 44%, from expected goals of 1.64 and 1.89.
The league sets the starting point. Promotion League has produced over 2.5 goals in 69% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Cham have 3 in 5 this season (2 of 4 at home), Zürich II 4 in 5 (2 of 2 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 66% and 72%.
Last season still counts, briefly. With 5 and 5 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 69% and 67%.
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 68%.
Head to head. These sides have met 6 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 68%.
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 69%, from expected goals of 1.64 for Cham and 1.89 for Zürich II. Folding in 30% of that view gives 68%.
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.
