Pro League · Sunday, 11 October 2026. Final score 1–1 (half-time 0–1). Before kick-off we rated it 52% over 2.5 goals — the match finished with 2, so that call missed. That rating was frozen into a version-controlled ledger before the game and has not been touched since.

The league sets the starting point. Pro League has produced over 2.5 goals in 51% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Union St. Gilloise have 5 in 7 this season (2 of 3 at home), OH Leuven 4 in 7 (2 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 56% and 53%.
Last season still counts, briefly. With 7 and 7 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 47% and 49%.
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 49%.
Head to head. These sides have met 5 times in three years, producing over 2.5 goals in 20%. 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 47%.
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 56%, from expected goals of 2.58 for Union St. Gilloise and 0.34 for OH Leuven. Folding in 30% of that view gives 50%.
Calibration. Tested against 97,729 past matches, our ratings below 55% have run consistently too pessimistic — a figure in the high 30s, for instance, has come in about four points higher. So ratings in that range are lifted part-way back, giving 51%.
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.
