A1C went from 7.4 to 5.6 over nine months and my prescriber was more interested in the fasting insulin, which I did not expect.
The bit I cannot resolve on my own is why A1C lags the way it does, and what to look at in the meantime if you want to know sooner.
If the honest answer is that nobody knows, that is a useful answer and I would rather have it.

My labs after 3 months on glycaemic control: A1C 5.4%, fasting glucose 79 mg/dL, fasting insulin 8 uIU/mL. My endo says these are "textbook perfect."
For context, my baseline A1C was 7.3% and fasting glucose was 114 mg/dL. The improvement has been dramatic and consistent.

Glycemic variability as the key metric for glycaemic control success: my coefficient of variation (CV) on CGM dropped from 41% to 21%. Target is <36%, with <30% being ideal.
Why this matters more than average glucose: large glucose swings cause oxidative stress, endothelial damage, and promote advanced glycation end-products (AGEs). A flat glucose line at 95 mg/dL is metabolically healthier than oscillating between 60 and 160, even if the average is the same.

This matches mine closely enough to be worth saying so out loud. The detail I would add is minor and it is already implied above.
From the other side of the consultation, briefly.
Complete metabolic panel trending on glycaemic control — sharing because comprehensive data helps everyone:
| Test | Baseline | Month 3 | Month 6 | Month 12 |
|---|---|---|---|---|
| Glucose (fasting) | 114 | 104 | 90 | 82 |
| Insulin (fasting) | 20 | 12 | 10 | 5 |
| HOMA-IR | 4.5 | 4.0 | 1.8 | 1.3 |
| Uric Acid | 8.7 | 6.4 | 5.7 | 5.0 |
The insulin resistance improvement (HOMA-IR) is what my endo focuses on most. Going from 4.5 to near 1.0 is a metabolic transformation.
