All the blues look nice, Paula. But it is strange she had an inverse curve yesterday.
You might have a look at Misty's spreadsheet. She is having better luck not shooting numbers under 150 or so. If she gets a dropping number under her target for amps, she waits and shoots it when it moves up into her target range. This usually happens close to pmps or even amps the next cycle. It's as though the insulin is more than the cat needs and her numbers are better without it, until she is in a range where she does need it.
Not sure it would work that way for PJ but you might try it and see.
