Re: 5/27 Lucian AMPS 438,+3.5/192
hmmm, yeah he is.
I have two thoughts after yesterday, one about R and one about food. Forgive me, I haven't studied ALL of Lucian's spreadsheet, just the last week or so, so there may be something I am missing. It looks like he rose 150 points after his +10 snack early this morning, and I see similar cycles on other days. For some cats, feeding at the end of the cycle can really affect their preshots. You are giving food at a time when the exogenous insulin is at its weakest, so if he is a good food spiker there might not be enough insulin to overcome that food. Can you move his late snack to be earlier in the cycle instead of +9 or +10? Or maybe give just a small spoonful or even a no carb chicken treat to tide him over.
About the R, assuming that this fast drop will set off another bounce, then you might have another opportunity to use R today. If you'll be home this afternoon, I would watch for the rise to begin and hit him with 0.1u of R. Do it as soon as you catch a decent rise beginning, as long as it is after+7. Depending on what he does, you might even be able to give another drop at +11 or PMPS.
I'm leaving for the rest of the day, but my PMPS is about the same time as yours so I'll try to check in later to see what happened today.
