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: Arda Kardzhali 1.95, draw 3.30, Botev Plovdiv 3.70.
The league sets the starting point. First League has produced over 2.5 goals in 44% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Arda Kardzhali have 2 in 7 this season (1 of 3 at home), Botev Plovdiv 3 in 7 (1 of 3 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 41% and 43%.
Last season still counts, briefly. With 7 and 7 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 39% and 50%.
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 44%.
Head to head. These sides have met 9 times in three years, producing over 2.5 goals in 33%. 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 43%.
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 43%, from expected goals of 1.67 for Arda Kardzhali and 0.74 for Botev Plovdiv. Folding in 30% of that view gives 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.
