The result model puts Cobresal at 48%, the draw at 24% and Palestino at 28%, from expected goals of 1.71 and 1.27.
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. Cobresal have 11 in 19 this season (4 of 9 at home), Palestino 11 in 19 (6 of 9 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 53% and 56%.
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 54%.
Head to head. These sides have met 6 times in three years, producing over 2.5 goals in 83%. 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 57%.
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 57%, from expected goals of 1.71 for Cobresal and 1.27 for Palestino. Folding in 30% of that view gives 57%.
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.
