National League · Tuesday, 29 September 2026. Final score 3–1 (half-time 2–0). Before kick-off we rated it 62% 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 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. Boreham Wood have 9 in 10 this season (4 of 4 at home), Kidderminster Harriers 3 in 10 (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 67% and 50%.
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 65% and 50%.
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 58%.
Head to head. These sides have met 2 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 57%.
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 2.23 for Boreham Wood and 1.17 for Kidderminster Harriers. Folding in 30% of that view gives 60%.
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.
