Joan,
Your SS isn't a mess, it's fine. The important thing is that you got the information on it, which will help you (and us) out "down the road".
I wasn't here when all the questions were being asked, but here's my take after the fact -
If this happens again....
You can see that her number was on the way up from your first PM test. But that number was too low too shoot, right? Then you got the 191. Had I been on, I would have suggested that you shoot at that point. You'd have known for sure that the number was coming up still, and that it would continue to once you fed her, until the insulin "kicked in" a couple or three hours later. So you would have been okay shooting the smaller dose at the 191, and not waiting another 30 minutes. The reason that might help you out is that if you are trying to keep on a roughly 12 hour shot schedule, you would have only delayed for 30 minutes instead of 60.
Make sense?
One other observation.... Lucy looks like a "late nadir" kitty to me. On the days where the data is pretty full across her AM cycles, it seems like her nadir can happen often past +6. Not quite sure why, but we can work with it. When does she eat after the morning shot time during the day?
