The result model puts Palestino at 44%, the draw at 24% and Colo Colo at 32%, from expected goals of 1.68 and 1.42.
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. Palestino have 14 in 24 this season (7 of 12 at home), Colo Colo 14 in 24 (8 of 12 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 55%.
Last season still counts, briefly. With 24 and 24 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 55%.
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 5 times in three years, producing over 2.5 goals in 20%. 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 60%, from expected goals of 1.68 for Palestino and 1.42 for Colo Colo. Folding in 30% of that view gives 55%.
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.
