| Market | Price | Implied | Our rating | Edge |
|---|---|---|---|---|
| Over 2.5 goals | 2.08 | 45% | 43% | -2% |
| Under 2.5 goals | 1.73 | 55% | 57% | +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: BSK Banja Luka 2.38, draw 3.10, Zeljeznicar Sarajevo 2.70.
The league sets the starting point. Premijer Liga has produced over 2.5 goals in 38% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. BSK Banja Luka have 4 in 9 this season (2 of 4 at home), Zeljeznicar Sarajevo 3 in 9 (1 of 4 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 40% and 37%.
Last season still counts, briefly. With 9 and 9 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 43% and 36%.
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 39%.
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 45%, from expected goals of 1.48 for BSK Banja Luka and 1 for Zeljeznicar Sarajevo. Folding in 30% of that view gives 41%.
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 43%.
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.
