How the Dexcom G6 works?

I started a new sensor last night (got data at 5:30 pm) and got a 44 down arrow alarm at 11 pm. When I went to look at the numbers from last night today, the 44 didn’t show up on the Dexcom clarity program. Instead it had 55 at the same time. I’m certain the receiver showed 44, cause it scared me to death, and I have a clear mental picture of it, and even told my husband, wrote it in my log etc. But it doesn’t show up on the clarity program (on the computer). Is there something about how clarity processes the data?

My understanding is that G6 uses a “smoothing algorithm” that results in the differences.


@MM2 - Thanks, that makes sense.
