The result model puts Central Norte at 33%, the draw at 38% and CA Estudiantes at 29%, from expected goals of 0.76 and 0.68.
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. Central Norte have 5 in 24 this season (1 of 11 at home), CA Estudiantes 6 in 25 (3 of 12 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 23% 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 26%.
Head to head. These sides have met 3 times in three years, producing over 2.5 goals in 0%. 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 23%.
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 18%, from expected goals of 0.76 for Central Norte and 0.68 for CA Estudiantes. Folding in 30% of that view gives 22%.
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.
