I use half-hollows to wedges (mostly) and it's one pass "plus". i.e. I immediately splash some water or extra lather on the "rough" or missed spots and hit them a second time. I never shave ATG, but my neck hair grows more horizontally on the sides, so it's always XTG.
I get close to BBS on most days but it doesn't bother me at all if not. Fewer passes for me means less aftershave sting, which is my gauge of a nice shave.
