G6 calibration algorithm musings

Rarely check. it is so accurate, it seems like a waste of time. given that I’ve finger stuck myself literally more than 229,000 times over the years, I am so over doing it needlessly. :slight_smile:

How do you know if it accurate unless you check it against a meter? Did you do it for a few days and then stopped? I still stick 8X a day so hoping after testing accuracy of G5 and G6 at the same time, I will find I can stop too.

I think you are overthinking this. Day one for sure is problematic for many of us, but after that u should be fine if u test it once a day for your peace of mind.

What did you have before, G4 or G5?

More than 2-1/2 years on G5

I don’t get it. When you had the G5, they said calibrate twice in 24 hours but you tested a lot. Now they say you need not test because it is calibrated at the factory and you took their word for it and seldom test? It’s obviously, a personal thing. I’m going to test its accuracy as I am sure it is more accurate on some people than others.

I doubt you’ll find anyone on this board who just trusted the G6 blindly, let alone @Dave44. That’s not what he said. He said he found that his first day of both sensors was a little rough, but after that has been spot on. Hence, the innate NEED to test/verify constantly wears away as you see how accurate the G6 is. That trust is built over time, albeit briefer than you would expect for some of us.

I’m 4-5 months in, and trust it so completely that I get grouchy during the warmup periods, when I don’t have that data. That didn’t happen overnight, though. It took a few sensors before I learned how good it is for me.

Unfortunately, there are some whose body chemistry doesn’t play as nice with the system and still feel the need to test/calibrate often. You won’t know where you fall on that spectrum until you try it for yourself.

Wow, did you twist my words!!! I don’t “take their word for it”. that’s ridiculous. I said my sensors are accurate to the point where I don’t have to test a lot. When I do check, the sensor is very close to the meter readings. You are still overthinking this stuff!

I think u need to spend less time posting about this and just use your G6 and see from time to time if it is accurate. I can’t help you any further.

I shoot for 24 hours, but have gone as low as 6 without issue.

My apologies for misinterpreting your post. As I look back, I thought you were responding to my post regarding whether anyone soaks their G6 and for how long, and you mentioned that the G6 was accurate enough for you that you stopped a multitude of fingersticks.

I should have responded, “How did you, or anyone after switching to the G6, initially determine the G6 was accurate enough that they could significantly curtail finger sticks.”

No need to respond to me further. I acknowledge my error.

I determined when starting the G6 that it was accurate by doing a LOT of fingersticks for a few days. But after 30 days it is apparent that only on the first day is it flaky. Random checks coincide very well with the G6 numbers so it is pointless to prick my finger much. Hope that helps.

exactly. once in a while. :slight_smile:

Great, that is what I was hoping to hear about the G6.

Not every person will have the same results with any CGM model so it is up to each person to see how a particular model works for them. The G5 didn’t do well for my wife but it does great for me. She does well on the G6, however.

Totally agree. And even if one was to determine G5 or G6 was more accurate than the other, another testing period may prove just the opposite. So ultimately, at best, it is an educated guess.

For me the G6 is “more” accurate, but not by a huge amount. I’ve worn both at the same time for weeks and if I calibrate the G5 at least once per day it is very close to the G6 which means it is accurate. Others may have widely differing results due to body chemistry or over-calibrating, or not being hydrated enough, etc, etc.

Thanks, my G5 has been very accurate so very happy if G6 is close or more accurate.

At 7:30AM today, with the G5 10 hours from its last calibration, and the G6 installed 8 hours ago, here is the accuracy in a photo:
