Keep an eye on that avoidance behaviour associated with the insulin. It might be Nacho's way of telling you that the Vetsulin is making him feel bad (he's in fairly good numbers - potentially his body might be fighting the dose?).
I know that you've skipped tonight but is there any chance you could get a +2 or +3 test tonight to see whether Nacho's BG might have gone lower after his evening feed?
It might be worth considering dropping the dose down to 0.1IU for a few cycles to see how Nacho gets on, but don't lower your current 'no shoot' limit.
