The league sets the starting point. 1. Deild has produced over 2.5 goals in 70% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Grindavik have 8 in 19 this season (3 of 10 at home), HK Kopavogur 15 in 19 (8 of 10 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 74%.
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 66%.
Head to head. These sides have met 3 times in three years, producing over 2.5 goals in 100%. 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 69%.
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 48%, from expected goals of 1.49 for Grindavik and 1.11 for HK Kopavogur. Folding in 30% of that view gives 63%.
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.
