He dipped as late as +9 in the PM cycle of 11/11.
Will he eat a little if you were to give him a snack? We don't want him dipping below 50 at AMPS and skipping or delaying the shot.
I think you can feed him a snack and call it a night. You must be exhausted.
Maybe get a +11.5 so that you can post and ask for help with the AM shot, if needed.
