It's a difficult subject because everybody is different. The idea is to do the least you have to just like honing. If you are happy with a shave derived from 1 WTG pass then stop there. If you need the XTG use that where you have to and if you need ATG do that where you need it. If you're starting with any new routine experiment and just do a small area and see what happens, how your face tolerates it. it may take a while to get used to it.
