No offense taken at all, Brian.
One thing I think get's lost in many discussions is T1 vs. T2. I'm an unusual T2 because I voluntarily went on insulin, and (miraculously!) got approved for a CGM and pump.
I don't need these technologies to live, like a T1 does (or at least, insulin). However, I can not achieve my goals (normal, non-diabetic blood sugar) without these tools -- insulin, CGM, and pump.
Okay, so that said, some of the aspects of T2 make this a bit different than for T1s, particularly in the "resolution" of insulin. Because of insulin resistance, I have a much higher "resolution" (i.e. the amount of correction I can deliver in terms of reduced mg/dl is much tinier than T1s without IR). For example, my correction factor is 10 -- that is, 1U of insulin drops my BG 10 mg/dl.
Because of this, I can correct a 97 with 0.25U, then keep an eye on it. Or, temp basal +0.5U/hr, and then again watch it.
Also, I've found since I got these technologies that, below 150-170, the CF is pretty constant and reliable. If I wait the 3.5 hours insulin is active in me, I'll get nearly exactly the drop expected. This has led me to do some tentative experimentation a the fringes, like what we're discussing here.
The other big "experiment" has been correcting based just on the CGM (highs, that is) in some cases. Posted another discussion about that one.
