I had been stalking Yoshi’s spreadsheet.

I do love the change in colour scheme.

I can see you are having a hard time giving the same dose, which really does make figuring out the dose harder. Remember, we dose by nadirs with the depot insulins, not the preshots. Get rid of that Prozinc thinking of changing dose based on preshots. Also, keep remembering Lev means lower preshot numbers. Dosing by nadirs also means getting night time tests, even before bed, is super helpful.
The 7 unit depot is still influencing today. The larger depot influences 4-6 cycles after a reduction, the higher end for larger depots.
Some guidelines I have used, as have others with cats with acro. Hold the dose if you are seeing under renal threshold numbers, unless you see numbers below a reduction threshold that works for you. With my human meter I used 70 when Neko was coming down dose fast after treatment, 50 if she was holding mostly steady. If getting a second test, including nights, is going to be an issue for you, maybe start with 90 in the AT, as per SLGS. That would mean reducing to 6.5 after today. You have the weekend to gather more data and get rid of the 7 unit depot. Plus you’ll be on the line.
Over time you may tweak that 90 as a reduction point if you find his numbers start rising too much if you reduce then. Yoshi doesn’t look to be in what I would call a fast reduction phase. I rather suspect you broke through some glucose toxicity, which usually means some downward motion in dose, but then settles to the normal gradual ups and downs.
Most important, how is Yoshi feeling/behaving now that he’s in much better numbers?
