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: Airdrie United 3.40, draw 3.40, Ross County 1.91.
The league sets the starting point. League One has produced over 2.5 goals in 49% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Airdrie United have 1 in 3 this season (0 of 1 at home), Ross County 1 in 2 (0 of 1 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 47% and 48%.
Last season still counts, briefly. With 3 and 2 games played this season, last season's rates are still blended in and fade out entirely by game 14 — the point at which our testing showed they stop adding accuracy. That moves the two figures to 47% and 52%.
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 4 times in three years, producing over 2.5 goals in 75%. 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 52%.
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 41%, from expected goals of 1.27 for Airdrie United and 1.05 for Ross County. Folding in 30% of that view gives 49%.
