I think the reason he bounced was because he hadn't seen "green" in a while.
The number wasn't "too low" but his pancreas and liver felt like it was.
I like to fall back on the words of Dr. Lisa when this sort of thing happens. It basically comes down to "repeatability". If this keeps happening, then maybe the dose is a little strong. But if it isn't a pattern, then don't react to a one-time occurance by adjusting the dose.
The exception to that of course would be if you see numbers that drop below 50. In that case you should probably scale back the dose.
The reason I asked about food was to find out if the increase in BG that followed was the result of a boost from food.
At this point, I don't see "short duration" on your spreadsheet. Today, I see a dose that worked really well.
Whenever I saw a green number on Bob's meter, all I did was smile a lot. It can be nerve wracking, but as long as you know what to do to deal with low numbers when you need to, I think you're good to go.
I don't think I've seen a cat in the 3+ years I've been around that didn't "bounce". But eventually they stop doing so.
To me, sliding scales work well with Prozinc. They do require a good amount of historic data, and " instinct" on your part as well as mid-cycle tests whenever you can get them.
