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: Cucuta 5.75, draw 4.10, Atletico Nacional 1.53.
The league sets the starting point. Primera A has produced over 2.5 goals in 45% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Cucuta have 17 in 32 this season (8 of 15 at home), Atletico Nacional 23 in 37 (13 of 20 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 50% and 55%.
Last season still counts, briefly. With 32 and 37 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 50% and 55%.
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 51%.
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 53%, from expected goals of 1.07 for Cucuta and 1.73 for Atletico Nacional. Folding in 30% of that view gives 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.
