My entire face and neck gets a 3 pass shave.
1st pass: straight down.
2nd pass: atg on the sideburns, sideburns to middle of the face both sides, diagonal towards the chin on the neck.
3rd pass: straight up except for the mustache area, which is xtg with a slight upward motion.

I will sometimes (time permitting) re-lather and run my fingers over my face to ensure I mowed it all down & if need be touch up atg.

This is my same routine if I am using a DE as well, I just adjust the settings with each pass, from more aggressive to less aggressive.
