Bundesliga · Sunday, 11 October 2026. Final score 2–1 (half-time 1–1). Before kick-off we rated it 68% over 2.5 goals — the match finished with 3, so that call landed. That rating was frozen into a version-controlled ledger before the game and has not been touched since.

The result model puts 1. FC Köln at 60%, the draw at 21% and Borussia Mönchengladbach at 19%, from expected goals of 2.15 and 1.13.
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. 1. FC Köln have 3 in 4 this season (1 of 2 at home), Borussia Mönchengladbach 4 in 4 (2 of 2 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 66% and 70%.
Last season still counts, briefly. With 4 and 4 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 65% and 60%.
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 63%.
Head to head. These sides have met 2 times in three years, producing over 2.5 goals in 100%. 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 65%.
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 64%, from expected goals of 2.15 for 1. FC Köln and 1.13 for Borussia Mönchengladbach. Folding in 30% of that view gives 64%.
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.
