Wow!
I'm a little jealous of your spreadsheet.
It's not all over the place at all. (You want to see all over the place, check out mine, lol - we're working on it though.)
I'm so impressed Rocky stays within a hundred points.
I'm not familiar with how your insulin works so I'll leave the advice to others.
I just wanted to pop in and say, good job getting things set up and testing! Just keep collecting info and asking questions!
