Liga Profesional · Sunday, 10 May 2026. Final score 1–2 (half-time 0–1). Rebuilt from the season as it stood that morning, our rating would have been 47% 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 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. Independ. Rivadavia have 8 in 16 this season (6 of 9 at home), Union Santa Fe 8 in 16 (6 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 40% and 40%.
Last season still counts, briefly. With 16 and 16 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 38% and 36%.
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 3 times in three years, producing over 2.5 goals in 33%. 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 36%.
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 68%, from expected goals of 2 for Independ. Rivadavia and 1.52 for Union Santa Fe. Folding in 30% of that view gives 46%.
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 47%.
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.
