Primeira Liga · Saturday, 10 October 2026. Final score 1–2 (half-time 1–1). Before kick-off we rated it 56% over 2.5 goals — the match finished with 3, 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 Maritimo at 8%, the draw at 16% and FC Porto at 75%, from expected goals of 0.66 and 2.39.
The league sets the starting point. Primeira Liga has produced over 2.5 goals in 54% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Maritimo have 5 in 7 this season (2 of 3 at home), FC Porto 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 58% and 54%.
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 58% and 55%.
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 56%.
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 59%, from expected goals of 0.66 for Maritimo and 2.39 for FC Porto. 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.
