The result model puts Junior at 38%, the draw at 28% and Santa Fe at 34%, from expected goals of 1.19 and 1.11.
The league sets the starting point. Primera A has produced over 2.5 goals in 44% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Junior have 14 in 27 this season (8 of 14 at home), Santa Fe 13 in 26 (5 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 49% and 45%.
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 47%.
Head to head. These sides have met 8 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 47%.
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 40%, from expected goals of 1.19 for Junior and 1.11 for Santa Fe. Folding in 30% of that view gives 45%.
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.
