Nice!! I would guess that the red number you got this morning is a bounce from that lovely blue....Joey's body has gotten "used to" those high numbers and thinks they are normal, so when a nice low number comes along, the liver "panics" and tosses stuff into the bloodstream, thinking it's protecting the body from going hypo. Over time, the liver and pancreas learn to work together again, and the bounces become less pronounced.
I'm sure you've noticed how we all set up our subject lines...the date, the cat's name, followed by our AMPS/PMPS and subsequent tests. The best way to have more experienced eyes take a look at your spreadsheet and offer advice is to use that format, add the little question mark icon, and also note in the subject like that you have a question.
You're doing a great job!!!
