I do repeated short strokes on the ATG pass, not quite ad nauseam but until I don't feel there's any stubble left to cut - maybe 4 - 5 strokes (max) on any give patch of skin, although I don't find it necessary over mt whole face.

It really shows up the quality of the edge though - if it's a little harsh, more strokes = more skin irritation and burning from the aftershave.

Oh look, this could be it: buffing.
