Liga MX · Monday, 28 September 2026. Final score 2–4 (half-time 2–2). Before kick-off we rated it 52% over 2.5 goals — the match finished with 6, 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 Necaxa at 27%, the draw at 26% and Club America at 47%, from expected goals of 1.11 and 1.54.
The league sets the starting point. Liga MX has produced over 2.5 goals in 55% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Necaxa have 6 in 9 this season (4 of 5 at home), Club America 5 in 8 (2 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 58% and 57%.
Last season still counts, briefly. With 9 and 8 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 56% and 53%.
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 55%.
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 53%.
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 49%, from expected goals of 1.11 for Necaxa and 1.54 for Club America. Folding in 30% of that view gives 52%.
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.
