Maria -
Kahlua seems stuck in low blues high(ish) greens. I have two thoughts:
- fatten the dose so you'd be shooting a dose between 1.0u and 1.25u or
- try experimenting with giving a snack at around +8 or +9. It looks like Kahlua's pancreas is working and the snack may cause her pancreas to produce some insulin and drop the pre-shot numbers.
Just my 2 cents.....
