Scott, right now I’m going through a similiar process to yours - after 38 years of injections I started using a pump two weeks ago. I’m starting to finally see consistantly good BG values except for the 3AM - 8AM time slot.
As I’m sure you know that hardest part is to tweak a little and wait. Until you get repeatable patterns you can’t have any confidence in your changes so stick with it and in a couple of weeks you should be through the tough part (at least that’s what I keep telling myself).
