The result model puts Sport Boys at 52%, the draw at 27% and Sporting Cristal at 20%, from expected goals of 1.42 and 0.77.
The league sets the starting point. Primera Division has produced over 2.5 goals in 51% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Sport Boys have 6 in 22 this season (2 of 11 at home), Sporting Cristal 15 in 23 (6 of 12 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 37% 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 47%.
Head to head. These sides have met 6 times in three years, producing over 2.5 goals in 67%. 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 49%.
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 38%, from expected goals of 1.42 for Sport Boys and 0.77 for Sporting Cristal. Folding in 30% of that view gives 46%.
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.
