Primeira Liga · Saturday, 8 August 2026. Final score 1–0 (half-time 0–0). Before kick-off we rated it 58% under 2.5 goals — the match finished with 1, 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. Primeira Liga 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. Maritimo have 0 in 0 this season, Casa Pia 0 in 0. Those records are pulled toward the league rate with the weight of about 32 matches — enough that two or three unusual games cannot swing a rating — giving 53% and 53%.
Last season still counts, briefly. With 0 and 0 games played this season, last season's rates are still blended in and fade out entirely by game 14 — the point at which our testing showed they stop adding accuracy. That moves the two figures to 53% and 42%.
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 49%.
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 43%, from expected goals of 1.47 for Maritimo and 0.93 for Casa Pia. Folding in 30% of that view gives 47%.
Season opener. One of these sides has not played a league game yet. Openers run about 2.5 points under their league's norm, measured across 2,727 of them, so the rating is docked to 45%.
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.
