The result model puts Viking at 66%, the draw at 18% and Sarpsborg 08 FF at 16%, from expected goals of 2.44 and 1.12.
The league sets the starting point. Eliteserien has produced over 2.5 goals in 62% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Viking have 11 in 15 this season (6 of 6 at home), Sarpsborg 08 FF 7 in 15 (5 of 8 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 69% and 58%.
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 63%.
Head to head. These sides have met 6 times in three years, producing over 2.5 goals in 50%. 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 62%.
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 69%, from expected goals of 2.44 for Viking and 1.12 for Sarpsborg 08 FF. Folding in 30% of that view gives 64%.
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.
