National League · Tuesday, 29 September 2026. Final score 0–1 (half-time 0–1). Before kick-off we rated it 56% over 2.5 goals — the match finished with 1, so that call missed. That rating was frozen into a version-controlled ledger before the game and has not been touched since.

The result model puts Gateshead at 31%, the draw at 26% and Altrincham at 43%, from expected goals of 1.23 and 1.49.
The league sets the starting point. National League has produced over 2.5 goals in 58% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Gateshead have 6 in 10 this season (1 of 4 at home), Altrincham 8 in 10 (3 of 5 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 59% and 64%.
Last season still counts, briefly. With 10 and 10 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 61% 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 60%.
Head to head. These sides have met 6 times in three years, producing over 2.5 goals in 50%. 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 51%, from expected goals of 1.23 for Gateshead and 1.49 for Altrincham. Folding in 30% of that view gives 57%.
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.
