Bundesliga · Saturday, 19 September 2026. Final score 3–4 (half-time 1–2). Rebuilt from the season as it stood that morning, our rating would have been 61% for over 2.5 goals. This match is older than our frozen ratings ledger, which keeps 30 days, so that figure is a reconstruction from pre-match data rather than a number we published at the time — a distinction worth making, because only the frozen ones prove what we actually said beforehand.

The result model puts Borussia Mönchengladbach at 29%, the draw at 23% and FSV Mainz 05 at 48%, from expected goals of 1.47 and 1.94.
The league sets the starting point. Bundesliga has produced over 2.5 goals in 65% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Borussia Mönchengladbach have 3 in 3 this season (1 of 1 at home), FSV Mainz 05 2 in 3 (1 of 1 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 69% and 65%.
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 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 60% and 59%.
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 61%.
Head to head. These sides have met 4 times in three years, producing over 2.5 goals in 25%. 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 59%.
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 66%, from expected goals of 1.47 for Borussia Mönchengladbach and 1.94 for FSV Mainz 05. Folding in 30% of that view gives 61%.
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.
