. I’m thinking I should go down to 2.75u now?
Absolutely, that 48 was WAY less than the 90 reduction point.
I see you fed Ginger some low carb food when you got that low at +6. That will help to bring the BG levels back up and keep Ginger safer. You also should have tested again after that low, to see if it was still dropping or had come back up. Don't see that test on the SS - yet.
Notes on the SS of when you gave food, like that 1/4 can of FF at +6 are also helpful.
Remember, the Nadir or low in the cycle might not ALWAYS be at +6 so test a little before that, a little after that, to see how Ginger is doing. Try some +5 tests.
I think the change you did in eliminating the dry food has made a major difference. I would not be surprised if Ginger earns another dose reduction very soon.
