| Market | Yes | No | Our call |
|---|---|---|---|

| Over 3.5 goals | 20% | 80% | no pick |
| Both teams to score | 45% | 55% | No |
The result model puts Godoy Cruz at 60%, the draw at 22% and Almirante Brown at 18%, from expected goals of 1.94 and 0.95.
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. Godoy Cruz have 16 in 34 this season (11 of 17 at home), Almirante Brown 7 in 34 (5 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 40% and 25%.
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 39% and 25%.
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 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 55%, from expected goals of 1.94 for Godoy Cruz and 0.95 for Almirante Brown. 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.
| Team | Games | O2.5 | O3.5 | BTTS |
|---|---|---|---|---|
| Godoy Cruz | 34 | 47% | 18% | 50% |
| Almirante Brown | 34 | 21% | 12% | 29% |
Our numbers give this match a 57% chance of at least one goal before half-time and 21% of two or more. The Primera Nacional rates, last season and this season combined, are 56% and 20% (this season so far: 56% with a first-half goal, from 612 games). After the break: 68% for a goal and 27% for two or more (league 68% and 28%). Godoy Cruz's last 50 games had a first-half goal 68% of the time and a second-half goal 72%; Almirante Brown's last 50, 48% and 64%. A goal in both halves: 42% (league 40%). Highest-scoring half: second 41%, first 28%, level 31% — close to the league's usual split, because team form says little about which half is busier. Team form says less about a single half than about a full match, so these numbers stay close to the league's.
Every match ranked the same way: first half goals today · second half goals today · goal in both halves today · tomorrow.
