The league sets the starting point. Allsvenskan has produced over 2.5 goals in 52% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. IF Elfsborg have 10 in 22 this season (4 of 11 at home), Halmstad 8 in 22 (4 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 49% and 45%.
Last season still counts, briefly. With 22 and 22 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 53% and 47%.
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 50%.
Head to head. These sides have met 5 times in three years, producing over 2.5 goals in 40%. 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 50%.
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 54%, from expected goals of 2.09 for IF Elfsborg and 0.76 for Halmstad. Folding in 30% of that view gives 51%.
Calibration. Tested against 97,729 past matches, our ratings below 55% have run consistently too pessimistic — a figure in the high 30s, for instance, has come in about four points higher. So ratings in that range are lifted part-way back, giving 52%.
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.
