I went back to the beginning of this thread 3 months ago and read through it. On the positive side, you started this a little over 3 months ago, so part of this A1C was the beginning of using Afrezza, when you were just figuring things out.
If you go to the beginning and read through, you can see how you have made changes and adjusted, so keep in mind that this A1C includes part of your learning curve. So you have learned things about it in the past 3 months, and that can mean your next one can be better.
The learn and adjust keeps happening forever. Who among us can say they have figured it all out?!
Have you considered using BOTH Afrezza and injection? I think the rapid in-and-out of Afrezza, combined with the slower depletion curve of subcutaneous shots might be a good match.
Just as an example, imagine if rather than taking 2 puffs of an Afrezza 4 unit, 90 minutes apart, you did the 4 puff and did a 4 unit bolus at the same time at the beginning of the meal. Those two things together might cover both the faster foods, and the longer acting foods. That could prevent both the immediate rise and the rise that happens a few hours later.
