Hi when you want some advice or suggestions you should put
a ? first in your title then maybe Advice Needed
In your title that you have no you should put AMPS 126 not just PS

I'm am going to tag a few members for you to take a look at your SS
You need to test at least one more time after your PMPS test say around +5 or +6
I read in your post your vet suggested no shot under 250 I see some members don't agree with that, neither do I
From the SLGS sticky
Hold the dose for at least a week:
- Unless your cat won’t eat or you suspect hypoglycemia
- Unless your kitty falls below 90 mg/dL (5 mmol/L). If kitty falls below 90 mg/dL (5 mmol/L) decrease the dose by 0.25 unit immediately.
After 1 week at a given dose perform a 12 hour curve, testing every 2 hours OR perform an 18 hour curve, testing every 3 hours. Note: Random spot checks are often helpful to "fill in the blanks" on kitty's spreadsheet. The goal is to learn how low the current dose is dropping kitty prior to making dose adjustments.
- If nadirs are more than 150 mg/dl (8.3 mmol/L), increase the dose by 0.25 unit
- If nadirs are between 90 (5 mmol/L) and 149 mg/dl (8.2 mmol/L), maintain the same dose
- If nadirs are below 90 mg/dl (5mmol/L), decrease the dose by 0.25 unit
