The league sets the starting point. Primera Clausura has produced over 2.5 goals in 43% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Rubio NU have 13 in 37 this season (5 of 18 at home), Club Guarani 13 in 37 (6 of 18 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 38% and 38%.
Last season still counts, briefly. With 37 and 37 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 39%.
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 40%.
Head to head. These sides have met 3 times in three years, producing over 2.5 goals in 67%. 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 41%.
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 0.72 for Rubio NU and 1.34 for Club Guarani. Folding in 30% of that view gives 39%.
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 41%.
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.
