| Market | Yes | No | Our call |
|---|---|---|---|
| Over 2.5 goals | 66% | 34% | Over |
| Over 3.5 goals | 45% | 55% | no pick |
| Both teams to score | 64% | 36% | Yes |
The result model puts Heerenveen at 35%, the draw at 23% and NEC Nijmegen at 42%, from expected goals of 1.63 and 1.81.
The league sets the starting point. Eredivisie has produced over 2.5 goals in 64% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Heerenveen have 5 in 9 this season (2 of 5 at home), NEC Nijmegen 7 in 9 (3 of 4 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 62% and 68%.
Last season still counts, briefly. With 9 and 9 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 66% and 68%.
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 67%.
Head to head. These sides have met 5 times in three years, producing over 2.5 goals in 60%. 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 66%.
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 67%, from expected goals of 1.63 for Heerenveen and 1.81 for NEC Nijmegen. Folding in 30% of that view gives 66%.
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 |
|---|---|---|---|---|
| Heerenveen | 9 | 56% | 56% | 33% |
| NEC Nijmegen | 9 | 78% | 56% | 89% |
Our numbers give this match a 82% chance of at least one goal before half-time and 47% of two or more. The Eredivisie rates, last season and this season combined, are 81% and 44% (this season so far: 83% with a first-half goal, from 81 games). After the break: 86% for a goal and 58% for two or more (league 85% and 56%). Heerenveen's last 50 games had a first-half goal 80% of the time and a second-half goal 88%; NEC Nijmegen's last 50, 88% and 90%. A goal in both halves: 73% (league 69%). Highest-scoring half: second 44%, first 29%, level 27% — 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.
