The result model puts Olimpia at 54%, the draw at 25% and Vasco DA Gama at 21%, from expected goals of 1.59 and 0.9.
The league sets the starting point. Copa Sudamericana has produced over 2.5 goals in 43% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Olimpia have 9 in 21 this season (5 of 10 at home), Vasco DA Gama 12 in 22 (5 of 10 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 44% and 48%.
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 45%.
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 46%, from expected goals of 1.59 for Olimpia and 0.9 for Vasco DA Gama. 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.
