| Market | Price | Implied | Our rating | Edge |
|---|---|---|---|---|
| Over 2.5 goals | 3.50 | 27% | 33% | +6% |

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: Chacarita Juniors 2.45, draw 2.75, Atlanta 3.10.
The league sets the starting point. Primera Nacional has produced over 2.5 goals in 30% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Chacarita Juniors have 6 in 27 this season (4 of 13 at home), Atlanta 11 in 27 (6 of 13 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 27% and 37%.
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 31%.
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 37%, from expected goals of 1.17 for Chacarita Juniors and 1.01 for Atlanta. Folding in 30% of that view gives 33%.
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.
