Championship · Tuesday, 13 October 2026. Final score 4–0 (half-time 3–0). Before kick-off we rated it 53% over 2.5 goals — the match finished with 4, 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 Birmingham at 51%, the draw at 24% and Preston at 25%, from expected goals of 1.78 and 1.16.
The league sets the starting point. Championship has produced over 2.5 goals in 53% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Birmingham have 6 in 9 this season (3 of 4 at home), Preston 6 in 9 (3 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 57% and 57%.
Last season still counts, briefly. With 9 and 9 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 51% and 52%.
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 51%.
Head to head. These sides have met 3 times in three years, producing over 2.5 goals in 33%. 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 51%.
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 1.78 for Birmingham and 1.16 for Preston. Folding in 30% of that view gives 52%.
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 53%.
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.
