The result model puts Fortaleza FC at 33%, the draw at 30% and Atletico Nacional at 37%, from expected goals of 1.01 and 1.1.
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. Fortaleza FC have 10 in 23 this season (5 of 12 at home), Atletico Nacional 17 in 27 (9 of 15 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 43% and 54%.
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 48%.
Head to head. These sides have met 5 times in three years, producing over 2.5 goals in 80%. 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 51%.
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 35%, from expected goals of 1.01 for Fortaleza FC and 1.1 for Atletico Nacional. Folding in 30% of that view gives 46%.
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.
