The result model puts Valur Reykjavik at 55%, the draw at 19% and FH Hafnarfjordur at 26%, from expected goals of 2.5 and 1.7.
The league sets the starting point. Urvalsdeild has produced over 2.5 goals in 63% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Valur Reykjavik have 17 in 24 this season (11 of 12 at home), FH Hafnarfjordur 13 in 24 (6 of 11 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 67% and 59%.
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 67% and 60%.
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 64%.
Head to head. These sides have met 8 times in three years, producing over 2.5 goals in 75%. 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 64%.
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 79%, from expected goals of 2.5 for Valur Reykjavik and 1.7 for FH Hafnarfjordur. Folding in 30% of that view gives 69%.
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.
