I've done accuracy studies of the G6 for a submission to the FDA, and while it's true they do filter out spikes, they're never more than 5mg/dL off from the measured value (which itself is usually within 10% of the real value). Interstitial lags are closer to 5 minutes when you're not experiencing severe perfusion issues, which is more than close enough for making dosing decision, especially considering subcutaneous insulin has similar or longer lag times (depending on lots of things of course, and subject to an individual's own body).

Any diabetic can confirm for themselves my claim about the Dexcom G6's unacceptable persistent error states.

Simply compare the CGM with your glucometer (testing 8x per day, for example), and watch the CGM go wrong (and stay wrong) on day 5 or 6 of using the sensor.

I wish what you said was true. I would love to have a CGM that works better than a glucometer, but they don't exist yet. In particular, the Dexcom G6 is inaccurate in a harmful way.

I’m T1 and I use the G6. I used to regularly check against a glucometer multiple times a day (without calibrating) to check accuracy, and found no issues. A blanket statement such as “the Dexcom G6 is inaccurate in a harmful way” is certainly not true in general, even if true for you.
