Michelle,
I actually agree with your logic regarding the skinny .5 dose on a low number. Looking at your spreadsheet, it doesn't look like lately he has gotten much movement from doses of .5 or 1.0, so I understand how you were thinking this morning,
Had you seen another day like the past few days, with flattish yellow cycles, I was ready to suggest a dose increase.
I routinely gave insulin to Bob on numbers much lower than most people advise. But only after weeks of treatment. But I gave him .5u on numbers like you saw this morning. However, I had been giving him 4u previously and I had a pretty good feel for how he reacted to a dose.
At this point, you don't have the data yet to anticipate what could happen.
Anyway, what I'm trying to tell you is that it wasn't necessarily a "bad call" this morning. You made a logical decision, and you were planning on being able to monitor and react if needed to a low number. I don't know that I would consider shooting a normal-range number though. Maybe down the road, when you're almost to the point of trying an OTJ trial, and you're talking about a couple drops of insulin.
I might dose my cat differently than I would advise you to dose yours, because I don't feel comfortable putting him at risk. But I wouldn't have an issue with advise a tiny dose on a BG of 150, for instance, provided it was logical based on your spreadsheet data.
It wasn't this morning's shot that gave you the odd numbers and bounce today. The bounce started too soon for that. It takes Prozinc two or three hours to start to onset. The bounce showed up before the AM dose had a chance to kick in. The low number that caused the bounce had to have happened sometime before the AMPS reading.
Tonight's number is encouraging. It could be that the bounce is already starting to clear out.
