To clarify:
In a post on the NAMSA forum, Pitchpoledave suggested using the H-division boundaries.
On the open forum, I suggested using the Alter Cup(USSA) boundaries and NAMSA Fleet designations.
I have copied my post over to the NAMSA forum under Dave's post.

Since this thread is a positive discussion about implementing NAMSA, let's move this discussion over there and leave all this H-bashing negativity here.
