I just switched to a new G6 sensor this a.m. after a full two sessions (20 days) on the previous one. AFAIK I could have rolled on to a third session, but I figured a full double was long enough. Didn’t notice any degradation of accuracy; the only thing that did seem to be an issue was that I started getting dropouts the last 4-5 days. One thing about the G6 that has impressed me is how very few of those I’ve been seeing as compared to the G5. Really just about zero until this last string of maybe three over four days.
Someone suggested somewhere that connection losses could be caused by the sensor somehow, not the transmitter as such, but that doesn’t make sense to me. It’s the transmitter that’s maintaining the Bluetooth connection—hence “transmitter”—and I wouldn’t have thought the sensor could have any effect on that. I’d be interested to hear what anyone else thinks.
