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. Biel-Bienne have 2 in 5 this season (2 of 2 at home), Young Boys II 5 in 5 (3 of 3 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 67% and 75%.
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 67% and 65%.
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 5 times in three years, producing over 2.5 goals in 80%. 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 82%, from expected goals of 2.87 for Biel-Bienne and 1.57 for Young Boys II. Folding in 30% of that view gives 72%.
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.
