The league sets the starting point. Primera Nacional has produced over 2.5 goals in 29% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Atletico Mitre have 9 in 23 this season (4 of 11 at home), Defensores De Belgrano 5 in 22 (3 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 34% and 27%.
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 30%.
Head to head. These sides have met 5 times in three years, producing over 2.5 goals in 20%. 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 29%.
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 30%, from expected goals of 0.87 for Atletico Mitre and 1.04 for Defensores De Belgrano. Folding in 30% of that view gives 29%.
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.
