The league sets the starting point. Super 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. FC Basel 1893 have 6 in 8 this season (3 of 4 at home), FC ST. Gallen 6 in 8 (2 of 4 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 70% and 70%.
Last season still counts, briefly. With 8 and 8 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 70%.
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 9 times in three years, producing over 2.5 goals in 56%. 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 67%.
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 60%, from expected goals of 1.4 for FC Basel 1893 and 1.71 for FC ST. Gallen. Folding in 30% of that view gives 65%.
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.
