[QUOTE="Diamattic, post: 1001572, member: 138639"] The '???' is not from rapid BS change, its from poor filament data. You get it during exercise likely because your moving around a lot and its affecting the filament placement under the skin which is causing the receiver to get 'strange' data. I can do my most intense workout and have it be fine the entire time only to get ??? as soon as i sit down and start stretching lol I typically get an influx of ??? when my sensor is about to fail around day 17+ . I usually wait it out however long it takes even if its hours (usually its at least an hour to two) but the problem is you are supposed to calibrate it once it resumes. So if you are getting these ??? twice a day, not only are you not seeing data but your finger picking much more then youd like on a CGM. At that point i might as well not even be wearing the thing if i have to finger pick in the morning and night, before meals, and then whenever it resumes from the ??? zone.. Only once so far have I 'restarted' my sensor due to ???. It was happening a lot and the restart actually really helped. The problem with a restart though is the algorithm that occurs during the 2 hour 'startup window' reduces accuracy and sensitivity every time, so the more restarts you have then less you can rely on the CGM. So avoid restarts whenever possible, much more happens then just 2 hours of down time. The key to long sensor life i have found is all about keeping the sensor in tightly in place and dry. Showers/baths/sweat is your enemy (for me anyway) I do my best to keep it out of direct water, and change my extra adhesive covering patch every 4-5 days to match sure its on there as solidly as possible lol [/QUOTE]
