Is Standard Deviation more important than average BG or Time-In-Range?

Question re: how lab a1c is calculated…

@ClaudnDaye

IF the low A1C is being achieved with a large number of severe lows then that isn’t healthy either.

But based on another thread

@Eric

The A1C, it is not a measurement of average. So lows don’t reduce it. A1C is a measurement of the amount of glucose that has bonded to the hemoglobin. So “average blood sugar” when used to describe A1C is somewhat over-simplified

So it seems that a1c does not get effected by lows, and in fact, they are not even considered. I guess one might assume a PWD has lows if there avg BGs is rather high, but their a1c is lower than what would be expected. Is that the reasoning??
