The only reason the Netherlands has that high a number, is because of the hill on which the Dutch, German, and Belgian borders meet. If you take Limburg out of the equation, the next highest point is 110 meters.
In two of the Dutch provinces, the highest point is a garbage dump hill.
According to wikipedia, Noord Brabant and Drenthe. My “research” hasn’t gone any deeper than that.
