Serie A · Saturday, 8 August 2026. Final score 2–1 (half-time 0–1). Before kick-off we rated it 54% under 2.5 goals — the match finished with 3, so that call missed. That rating was frozen into a version-controlled ledger before the game and has not been touched since.

The result model puts Gremio at 43%, the draw at 28% and Sao Paulo at 29%, from expected goals of 1.27 and 0.98.
The league sets the starting point. Serie A has produced over 2.5 goals in 47% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Gremio have 8 in 20 this season (4 of 10 at home), Sao Paulo 8 in 20 (4 of 11 away). 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 44% and 43%.
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 44%.
Head to head. These sides have met 6 times in three years, producing over 2.5 goals in 50%. That nudges the number 10% of the way toward the head-to-head pattern — deliberately small, because fixtures change more than reputations do — landing on 45%.
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 39%, from expected goals of 1.27 for Gremio and 0.98 for Sao Paulo. Folding in 30% of that view gives 43%.
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.
