The result model puts Midland at 48%, the draw at 32% and Gimnasia Y Tiro at 20%, from expected goals of 1.18 and 0.66.
The league sets the starting point. Primera Nacional has produced over 2.5 goals in 31% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Midland have 10 in 34 this season (3 of 17 at home), Gimnasia Y Tiro 11 in 34 (8 of 17 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 30% and 32%.
Last season still counts, briefly. With 34 and 34 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 30% and 31%.
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%.
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 28%, from expected goals of 1.18 for Midland and 0.66 for Gimnasia Y Tiro. 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.
