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. Gimnasia Y Tiro have 7 in 25 this season (2 of 13 at home), Chacarita Juniors 5 in 25 (2 of 13 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 26% and 23%.
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%.
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 28%, from expected goals of 1.29 for Gimnasia Y Tiro and 0.54 for Chacarita Juniors. Folding in 30% of that view gives 26%.
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.
