Bookmaker prices and where we differ

MarketPriceImpliedOur ratingEdge
Over 2.5 goals1.2575%77%+2%
Under 2.5 goals3.7525%23%-2%

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: Selfoss 2.00, draw 4.10, Fjolnir 2.70.

How we got this number

The league sets the starting point. 2. Deild has produced over 2.5 goals in 69% of its matches, and that is where a team with no record of its own would sit.

Each side's own record. Selfoss have 13 in 16 this season (7 of 7 at home), Fjolnir 14 in 16 (7 of 7 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 76% and 78%.

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 76%.

Head to head. These sides have met 3 times in three years, producing over 2.5 goals in 67%. 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 75%.

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 84%, from expected goals of 2.55 for Selfoss and 2.05 for Fjolnir. Folding in 30% of that view gives 77%.

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.
