Implied percentages have the bookmaker's margin removed, so they add to 100 and can be compared with our rating directly. Edge is simply the gap between the two. A positive edge means our model thinks the outcome is likelier than the price suggests — it is not a tip, and a high probability with a negative edge is a poor bet however safe it looks. Prices are a pre-match snapshot from a single bookmaker and move constantly.
Match odds: Ulsan Hyundai FC 2.15, draw 3.25, Gangwon FC 3.10.
The league sets the starting point. K League 1 has produced over 2.5 goals in 46% 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 13 in 22 this season (8 of 11 at home), Gangwon FC 7 in 21 (4 of 11 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 55% and 40%.
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 48%.
Head to head. These sides have met 9 times in three years, producing over 2.5 goals in 56%. 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 48%.
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 44%, from expected goals of 1.13 for Ulsan Hyundai FC and 1.3 for Gangwon FC. Folding in 30% of that view gives 47%.
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.
