Thats' the only splitpoint the pre-discretized tree has

Hi AP,

the example process isn't really helpful in showing the discretization.

An extreme example can be seen if the prepruning step is removed from the Decision Tree inside the Decision Tree (Multiway).

You can also add an Breakpoint after the inner Decision Tree to see the Tree before the discretization.
