Serie B · Sunday, 31 May 2026. Final score 2–0 (half-time 1–0). Rebuilt from the season as it stood that morning, our rating would have been 45% 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 result model puts Sport Recife at 49%, the draw at 26% and Nautico Recife at 25%, from expected goals of 1.56 and 1.06.
The league sets the starting point. Serie B has produced over 2.5 goals in 40% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Sport Recife have 4 in 10 this season (2 of 5 at home), Nautico Recife 4 in 10 (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 40% and 40%.
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%.
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 1.56 for Sport Recife and 1.06 for Nautico Recife. Folding in 30% of that view gives 43%.
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 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.
