The mandatory win probability model uses the four available 1X2 odds sets as a baseline. After converting the average odds to implied probabilities and normalizing to remove the bookmaker margin, the baseline was 34.1% for a Zwaluwen win, 29.5% for a draw, and 36.4% for a Purmersteijn win.
We then adjust for team form, home advantage and the single-game knockout context. Final outcome probabilities are:
Conclusion: Purmersteijn are the more likely winner, but only by a small margin. Zwaluwen's strong 7-0 KNVB Beker result and home factor keep this very close.
