The league sets the starting point. Promotion League has produced over 2.5 goals in 68% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Young Boys II have 9 in 10 this season (3 of 4 at home), Cham 6 in 10 (1 of 3 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 75% and 66%.
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 66% and 68%.
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 6 times in three years, producing over 2.5 goals in 33%. 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 66%.
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 58%, from expected goals of 1.54 for Young Boys II and 1.48 for Cham. 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.
