Carioca · Sunday, 8 March 2026. Final score 5–2 (half-time 0–0). Rebuilt from the season as it stood that morning, our rating would have been 41% for over 2.5 goals. This match is older than our frozen ratings ledger, which keeps 30 days, so that figure is a reconstruction from pre-match data rather than a number we published at the time — a distinction worth making, because only the frozen ones prove what we actually said beforehand.

The league sets the starting point. Carioca has produced over 2.5 goals in 41% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Portuguesa RJ have 2 in 11 this season (0 of 5 at home), CFRJ / Maricá 6 in 11 (2 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 34% and 46%.
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 40%.
Head to head. These sides have met 3 times in three years, producing over 2.5 goals in 33%. 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 40%.
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 34%, from expected goals of 1.15 for Portuguesa RJ and 0.92 for CFRJ / Maricá. Folding in 30% of that view gives 38%.
Calibration. Tested against 97,729 past matches, our ratings below 55% have run consistently too pessimistic — a figure in the high 30s, for instance, has come in about four points higher. So ratings in that range are lifted part-way back, giving 41%.
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.
