Primera Nacional · Sunday, 26 July 2026. Final score 2–1 (half-time 2–1). Rebuilt from the season as it stood that morning, our rating would have been 33% for over 2.5 goals. This match is older than our frozen ratings ledger, which keeps 30 days, so that figure is a reconstruction from pre-match data rather than a number we published at the time — a distinction worth making, because only the frozen ones prove what we actually said beforehand.

The result model puts Godoy Cruz at 67%, the draw at 24% and Central Norte at 9%, from expected goals of 1.63 and 0.42.
The league sets the starting point. Primera Nacional has produced over 2.5 goals in 29% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Godoy Cruz have 6 in 20 this season (5 of 10 at home), Central Norte 4 in 20 (3 of 11 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 29% and 25%.
Last season still counts, briefly. With 20 and 20 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 29% and 27%.
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 28%.
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 34%, from expected goals of 1.63 for Godoy Cruz and 0.42 for Central Norte. Folding in 30% of that view gives 30%.
Calibration. Tested against 97,729 past matches, our ratings below 55% have run consistently too pessimistic — a figure in the high 30s, for instance, has come in about four points higher. So ratings in that range are lifted part-way back, giving 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.
