The result model puts Atletico Nacional at 59%, the draw at 23% and Independiente Medellin at 18%, from expected goals of 1.87 and 0.94.
The league sets the starting point. Primera A has produced over 2.5 goals in 45% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Atletico Nacional have 23 in 37 this season (10 of 17 at home), Independiente Medellin 20 in 33 (10 of 15 away). Those records are pulled toward the league rate with the weight of about 24 matches — enough that two or three unusual games cannot swing a rating — giving 55% and 54%.
Last season still counts, briefly. With 37 and 33 games played this season, last season's rates are still blended in and fade out entirely by game 40 — the point at which our testing showed they stop adding accuracy. A single season is part luck, so each club's record is first pulled toward the league average by 34 games' weight. That moves the two figures to 55% and 52%.
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 52%.
Head to head. These sides have met 11 times in three years, producing over 2.5 goals in 64%. That nudges the number 5% of the way toward the head-to-head pattern — deliberately small, because fixtures change more than reputations do — landing on 53%.
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 53%, from expected goals of 1.87 for Atletico Nacional and 0.94 for Independiente Medellin. Folding in 30% of that view gives 53%.
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.
