I registered just to say that I was just struggling with this myself. The NROI post is quite clear, and after spending a while messing around with the P+'s hanger, I don't see how it can possibly conform to production/CO rules. My overlays make it seem like it is off by 1/4" (not exaggerating). Even without accounting for an inner belt, I can't reach any grip from the hanger at the point of attachment.
