The result model puts Huachipato at 27%, the draw at 21% and Colo Colo at 52%, from expected goals of 1.53 and 2.17.
The league sets the starting point. Primera has produced over 2.5 goals in 52% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Huachipato have 14 in 20 this season (10 of 10 at home), Colo Colo 13 in 21 (7 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 66% and 58%.
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 60%.
Head to head. These sides have met 5 times in three years, producing over 2.5 goals in 60%. 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 60%.
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 71%, from expected goals of 1.53 for Huachipato and 2.17 for Colo Colo. Folding in 30% of that view gives 63%.
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.
