My low/high range is 60-140 mg/dL, and my target BG is 83 mg/dL.
60 day standard deviation is 22 mg/dl and average glucose is 95 mg/dL. 98% of my readings are within range.
Most recent A1C was 4.6. For the majority of my career as a T1D I either didn’t know or care much about my A1C. Only in the past 15-20 years has maintaining tighter control become important to me. SD and TIR are more important to me than A1C.
I feel the “safe” zone A1C numbers of 7-ish my doctor(s) recommended for years are neither safe nor acceptable if one wants to avoid long-term complications.
