Lisa -
Let me make a suggestion that will take the pressure off. Follow SLGS. There is more flexibility with that dosing method compared to TR. TR is a protocol that has a research base and for a variety of reasons, it works best if you stick with the the "rules." SLGS was developed here and there is considerably more flexibility. You don't need to test as much and we're more likely to try to figure out how you're approaching testing/dosing vs calling you out because you're not following a protocol. (TR is a protocol vs SLGS which is a method, if that makes a difference.) The challenge with SLGS is that it would be helpful if you can get a curve.
You have your hands full. Take the easier approach. Buzzy's numbers look good. If you decide to switch to SLGS, remember to change the information in your signature.
