When you increase after just holding the dose for 6 cycles, it's very important that we have an idea how low that dose is taking the cat. That is why TR requires two tests per cycle, the preshot and one other. To make sure it is safe to increase so quickly. I see only two mid cycle tests for the 7 cycles you were at 4.0 units. Please try to get at least 4 tests per day moving forward. We want to make sure you are increasing safely.
It's often cats will see some temporary higher numbers the first couple cycles after an increase, it's a phenomenon we affectionately call New Dose Wonkiness. Cats often don't show you what the dose can do until the 4-5th cycle, as the new depot has to build.
Here's the link to your previous post, which we include for continuity:
