Yep, great guide Pants. I know a lot of it has helped me plan some of my play already. I had actually tried grinding earlier and ran into the same issue BLOMBOMB. As I discovered as long as I made at least one Analog kill with a melee weapon before going off on a shooting or driving rampage then the kills counted fine, but just loading the game, switching to Analog and going for a drive/shooting spree would result in no increase.
