If I EVER saw 91% TIR, I would be ecstatic. Congratulations!!! You are a superstar in my book!!!
To me all lows are not equal: there is the scary crashing low and there is the coasting, grazing, just barely hit 70 type of low. We all know the difference and know that a crashing low is the really scary situation. Interestingly, however, a grazing low, in my experience, often results in longer total time below 70 than an “oh, my, I’m crashing …” low.
Finally, in terms of getting hollered at:
I was in a car accident one time. Fortunately, I was not hurt even though I “rolled to a stop the hard way” … 5 1/2 roll overs. My only issue: 3 hours of memory loss.
Well, upon telling my endocrinologist that I had been in an accident, he REALLY let me have it: “Face the truth! You blacked out at the wheel …”
Because of my memory loss, I had no idea what had happened until I received and read the CHP (California Highway Patrol) accident report 10 days later: it turns out that another driver swerved in front of me, clipped my bumper, and caused my rollover accident. That was the first time that I even realized that another car was involved. The other driver was cited for an unsafe lane change, their insurance company paid for my totaled vehicle … and, best of all: I showed a copy of the CHP accident report to my endo and he profusely apologized for ASSUMING that a T1D in a car accident was AUTOMATICALLY at fault!
Have a good day … and congratulations on your excellent control!!!
