Wow, looking really awesome! My guess is the duration might be a little slim on this one, like what you saw last night, but still, looking good! I'm thinking you might need to edge the dose up a teensy bit, like 0.9 or maybe 1u on the next PS like this one (definitely not more than that though!). Nadir has a little room to be lower, though still very nice today! You are doing great! I'm so happy to see him doing well on less insulin - sometimes they just go all reds like he used to, so big yippee for all this great progress he has made!!!
As for analysis (my fave word! :mrgreen: ) it's hard to really match up very many kitties 1 to 1, seems like they all have variations and sometimes what works with one backfires with another. In this case I think there may have been a combo of actual rebound from the steep drops, and also liver training needed since he hadn't seen many good #s. So I'm thinking now that his liver has seen some stretches of good #s that reduced his insulin needs, so now the lower doses are still working well, and with the steep drops out of the picture the PSs are improving due to no more rebound. I'm guessing the higher PS last night was from less duration on the lower dose though. It's a balancing act! Anyhow, that's my speculation on all of it, if it made any sense.
