party_cat Happy Birthday Loki.
Hard to tell what is happening at night. I know you have experimented with food overnight, but I wonder if a snack at +6 might help a lower number if that is what is causing the higher amps. (can't remember if you have a automatic feeder). The other thing to try might be a tiny bit less insulin at night. (you are giving the same dose for a low 200 as a high 300). I know we wanted to try a consistent dose, but we are getting big fluctuations.
Maybe this weekend, plan a night curve?
