@Allen3 - That's a very good day, by the way.Your overnight line is tremendous. I use Afrezza 4's mostly for corrections. They serve me well. If I need more than a 4-unit Afrezza correction I will often add a 2 or 4 unit IM or intramuscular dose. I think that combination works well as the Afrezza gets to work right away and the IM has a nice follow-through. Every once in a while I use two 4-unit Afrezzas for a special treat.
Don't get overly focused on the A1c number. It's not nearly as precise as we think it is with its decimal point apparent precision. The A1c has been a good statistic to make conclusions about a population of diabetics. It's not so precise about drawing a valid picture of a single individual.
Check out this diaTribe article entitled Going Beyond A1c - One Outcome Can't Do It All.
In the article they reproduce a table that shows that the A1c is not just equivalent to one specific average blood glucose, instead it's equivalent to a wider range than you think. A 6.0% A1c is actually equivalent to 100-152 mg/dL. Here's that table:
This article caught my eye because my CGM Clarity data with the equivalent A1c is often in the sub-5.5% A1c with the lab coming in around 6.0%. I have four goals to measure my glucose control and the A1c is not one of them.
