If I was home, I would definitely give the full dose of fat 1.75, but I won't be able to test. I have given her that dose with a blue preshot a few times.
It looks like she's on her way up. If it's been 20 minutes since the last test, why don't you test again (before feeding) and see if she has come up some more. Post the new test number and I'll try to help you decide.
