@Bandit's Mom, I'm ready to switch to FLS. Will start tomorrow.
Trying to make sense out of the AT2 vs FLS numbers - but you are so right. I don't think I can. I'll see how I can report the relationship in some reasonable way...
Congrats on breaking up with the AT2. I hope you're able to sell the remaining strips. You could keep a box of them as a back-up in case the FSL gives you any issues.
