The result model puts Excelsior Maassluis at 40%, the draw at 24% and Heerenveen at 37%, from expected goals of 1.7 and 1.64.
The league sets the starting point. KNVB Beker 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. Excelsior Maassluis have 0 in 0 this season, Heerenveen 5 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 64% and 62%.
Last season still counts, briefly. With 0 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 64% and 66%.
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 65%.
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 65%, from expected goals of 1.7 for Excelsior Maassluis and 1.64 for Heerenveen. Folding in 30% of that view gives 65%.
Season opener. One of these sides has not played a league game yet. Openers run about 2.5 points under their league's norm, measured across 2,727 of them, so the rating is docked to 62%.
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.
