Thank you for your feedback. 
I ran both songs through Moises and disabled the bass track in Garageband. I notice it as well during the walkdowns from C4. I wonder if Moises has issues when detecting bass in higher registers?
I’ll continue to work on timing - at least until it doesn’t have to be top of mind anymore, but fluidity is a fast follow. I especially notice it on my Come as You Are cover.

This is such a great hobby! I’m having a blast learning the craft and recording videos with my son. 
Edit: After working with the new Ray4HH a bit this morning, I’ve discovered that I’m out of tune on the low frets of the A string despite being in tune open and on the 12th fret. I’ll order a nut file and see if I can correct it next time I’m back here. I fly back to FL this evening.
