| Over 2.5 goals | 2.50 | 38% | 44% | +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: San Lorenzo 2.50, draw 2.90, Union Santa Fe 3.20.
The league sets the starting point. Liga Profesional has produced over 2.5 goals in 33% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. San Lorenzo have 3 in 21 this season (3 of 10 at home), Union Santa Fe 12 in 22 (8 of 12 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 26% and 46%.
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 36%.
Head to head. These sides have met 2 times in three years, producing over 2.5 goals in 50%. 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 37%.
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 59%, from expected goals of 1.52 for San Lorenzo and 1.52 for Union Santa Fe. Folding in 30% of that view gives 44%.
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.
