Ever had self adjusting brakes overtighten?

there's nothing wrong with adjusting brakes by backing up. I can't remember if it's in the owners manual, or if it's in the FSM, but it's in there. But good lord, it shouldn't take 50x! Two or three times should be sufficient.
I have read many service manuals but dont recall backing up to adjust brakes ever mentioned. Mind you, i only look at the pictures...
