Hi guys,
Woaaaaa Mala, get yourself of that trampoline, we all prefer to see you on that surf board.
It looks like she may have bounced from all that time in green, her body has probably got used to being in those icky pink numbers, and her liver has 'panicked' when she's got down into those nice greens, because her body is not used to these greens it perceives them as too low, this 'perceived' low can result in the liver dumping glucose into the blood stream causing the BG to spike, you will see a high flat curve for at least one cycle and the bounce may last up to 6 cycles but may clear earlier.
Sometimes when we feed extra food, in particular if it's higher carb later in the cycle, we can end up shortening the duration, this can see the numbers spike at PS but in contrast to a bounce you find that the numbers drop back down once the shot onsets.
Time and data will tell which it is, my guess is bounce, since from your notes it doesn't seem like you hit her over the head with carbs. ECID so it will depend on her sensitivity.
Will shoot the usual dose of .5.
BTW the ss says 5u

, guessing this is a typo, I nearly keeled over

On SLGS, she should have had a reduction, as she dropped below 90 and that is the reduction point for SLGS.
With bouncy kitties, we can sometimes shoot through the bounce as this can help them back on track more quickly, but we don't know yet if she is bouncy or not.
On TR you would be fine holding the dose, the reduction point being 50, and you guys are testing enough to do TR. It's best not to mix the two methods.
That said, given that Mala is out of remission, what we have found is that it is not unusual for folk to have to take a tighter hold on those numbers and be more aggressive with the dosing (within the guidelines) if they want to achieve regulation or even remission again. In my mind TR would offer you (from your posts it seems like you are hoping for another remission) the best chance of that as this protocol pushes kitty into the healthy range 50-80 and tries to keep them there, and we know that achieving this tight glycaemic control quickly, is what gives them the best chance of remission. In my opinion this is evidenced by the fact that more TR kitties go into remission than those on SLGS, doesn't mean it can't happen, it does, but it generally takes longer and fewer numbers achieve it.
Just my thoughts.
I was thinking when I looked at the ss this morning that 'I bet you're glad you didn't go with the 2u BID that the vet suggested

'
The Empress is looking great, you must be relieved to see those greens last night.
