I start at a sideburn and make short (2 - 3 inch) strokes. I stay in an area until I don't hear the sound of cutting anymore, then move down and repeat. Then do the other side. Then I feel my face and usually detect some stubble along the jaw line. I re-lather and hit the stubble again, with XTG and ATG strokes. Is that one pass and a clean-up? Multiple passes because I night go over a small area several times? How do you count "passes"?
