The result model puts Ulsan Hyundai FC at 20%, the draw at 20% and FC Seoul at 60%, from expected goals of 1.16 and 2.14.
The league sets the starting point. K League 1 has produced over 2.5 goals in 47% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Ulsan Hyundai FC have 16 in 26 this season (10 of 13 at home), FC Seoul 15 in 26 (9 of 14 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 58% and 54%.
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 9 times in three years, producing over 2.5 goals in 44%. 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 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 64%, from expected goals of 1.16 for Ulsan Hyundai FC and 2.14 for FC Seoul. Folding in 30% of that view gives 56%.
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.
