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: Rosenborg 2.45, draw 3.80, Viking 2.55.

How we got this number

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. Rosenborg have 8 in 16 this season (5 of 8 at home), Viking 12 in 16 (5 of 9 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 64%.

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 62%.

Head to head. These sides have met 6 times in three years, producing over 2.5 goals in 83%. 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 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 48%, from expected goals of 1.29 for Rosenborg and 1.31 for Viking. Folding in 30% of that view gives 59%.

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.
