Primera Nacional · Sunday, 4 October 2026. Final score 0–0 (half-time 0–0). Before kick-off we rated it 68% under 2.5 goals — the match finished with 0, so that call landed. That rating was frozen into a version-controlled ledger before the game and has not been touched since.

The result model puts Agropecuario at 59%, the draw at 26% and Midland at 15%, from expected goals of 1.58 and 0.65.
The league sets the starting point. Primera Nacional has produced over 2.5 goals in 30% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Agropecuario have 9 in 31 this season (4 of 15 at home), Midland 8 in 31 (6 of 15 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 28%.
Last season still counts, briefly. With 31 and 31 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 31% and 28%.
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 29%.
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 39%, from expected goals of 1.58 for Agropecuario and 0.65 for Midland. Folding in 30% of that view gives 32%.
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 35%.
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.
