Primera Nacional · Saturday, 30 May 2026. Final score 0–0 (half-time 0–0). Rebuilt from the season as it stood that morning, our rating would have been 38% 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 Racing Cordoba at 37%, the draw at 28% and Ferro Carril Oeste at 35%, from expected goals of 1.27 and 1.21.
The league sets the starting point. Primera Nacional has produced over 2.5 goals in 28% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Racing Cordoba have 8 in 14 this season (4 of 7 at home), Ferro Carril Oeste 3 in 14 (2 of 8 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 39% and 25%.
Last season still counts, briefly. With 14 and 14 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 36% and 26%.
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 30%.
Head to head. These sides have met 5 times in three years, producing over 2.5 goals in 60%. That nudges the number 5% of the way toward the head-to-head pattern — deliberately small, because fixtures change more than reputations do — landing on 32%.
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 45%, from expected goals of 1.27 for Racing Cordoba and 1.21 for Ferro Carril Oeste. Folding in 30% of that view gives 36%.
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 38%.
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.
