The result model puts Willem II at 33%, the draw at 22% and Heerenveen at 45%, from expected goals of 1.61 and 1.92.
The league sets the starting point. Eredivisie has produced over 2.5 goals in 62% of its matches, and that is where a team with no record of its own would sit.
Each side's own record. Willem II have 2 in 2 this season (1 of 1 at home), Heerenveen 1 in 2 (1 of 1 away). Those records are pulled toward the league rate with the weight of about 32 matches — enough that two or three unusual games cannot swing a rating — giving 65% and 63%.
Last season still counts, briefly. With 2 and 2 games played this season, last season's rates are still blended in and fade out entirely by game 14 — the point at which our testing showed they stop adding accuracy. That moves the two figures to 54% and 70%.
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 62%.
Head to head. These sides have met 2 times in three years, producing over 2.5 goals in 100%. That nudges the number 10% 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 69%, from expected goals of 1.61 for Willem II and 1.92 for Heerenveen. Folding in 30% of that view gives 67%.
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.
