One idea on my mind. It feels like many of us using CGM use a sensor for more than one week. If you could arrange to get a few dozen people to send you their readings for week one, two and three it would be interesting to see if there is a falloff in accuracy. Dexcom may supply, users may supply or allow you to “follow” and then the data would come directly to you.
My feeling is that week one and two work great but then in week three I get random ups and downs that I am assuming are because the sensor, under my skin, gets clogged in some form or fashion.
