DCNH does not work with functions but with elements. Dominant means strengthened Te and Fe, no matter in what position they are. The interesting thing is, the position of the strengthened functions seems to determine the shape of the face if my theory concerning
Visual Identification of Subtypes is correct. That makes it much easier to work with DCNH subtypes. Unfortunately, nobody on this forum seems to be able to confirm that. The problem is that we don't have English descriptions except for the
provisional ones which are not in all cases a good approximation...
Tcaudillg, during the last weeks I worked a lot with dual-types and some of the things you say actually make sense. What you still have to understand: Dual-type theory has to be logically consistent with the other subtype systems:
An INTj-INFp can only be a Ni-INTj if you want to use 8 subtypes.
A Ni-INTj can only be a H-INTj if you want to use 4 subtypes.
A Ni-INTj can only be a Ne-INTj if you want to use 2 subtypes.
