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. Chaco For Ever have 7 in 24 this season (4 of 11 at home), Los Andes 5 in 24 (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 30% and 26%.
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 28%.
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 32%, from expected goals of 0.92 for Chaco For Ever and 1.06 for Los Andes. 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.
