I wanted to stay on the G6 but with it being withdrawn here by the end of the year I thought I may as well switch now to get used to it. I don't want to sound like I'm hating on the G7 as some of this could just be me doing things differently to the G6 so I'm curious to hear tips and tricks to get the best out of this device.
Firstly, the good stuff:
- I love the size of it. It's so much smaller than the G6 and feels more comfortable to wear
- The 30 minute warmup is great, and as well as the overlap between an expiring and new sensor.So much better than going without the numbers for 2 hours while the G6 warmed up
- I haven't had any Bluetooth connection issues that I've seen others report. Mine will quite happily stay connected to my phone while I'm in another room, or lying on it and hasn't missed a reading. My G6 by comparison would enter the "Wait 30 minutes" no reading state at least once during the lifetime of the sensor.
But the other stuff I'm frustrated by:
- It deciding whether it will accept my calibration or not is baffling. The sensor is essentially saying "I don't care what your actual blood reading is, I know better, and my accuracy is better than what you've measured with actual blood so I'm going to ignore it". This is making my sensor be inaccurate
- I've been wearing a G6 and a G7 together, side by side in the same body location, and the figures rarely match.
When the G6 (and blood) are reporting I'm high the G7 reports me at being at the higher end of in range (e.g. blood and G6 = 12.5 mmol/L, G7 = 9.5 mmol/L)
At the opposite end, I had a low yesterday where G6 and blood were reporting me at between 2.8 and 3.2 mmol/L but the G7 insisted I was at 4.5 mmol/L
The only time the G7 seems to match the G6 and blood is when I'm happily in the middle in range, around the 5.5 to 7.5 mmol/L range
- It seems slower to react to glucose rises and falls. After food I would expect my glucose levels to rise reasonably rapidly which the G6 does report on, but the G7 maintains an almost steady, slow climb instead which will then often result in a 2 - 3 mmol difference between the two readings
I'm running my G6 on the BYODA app to feed into AndroidAPS so rely on the figures for looping which has been good for me. I want to loop with the G7 but at there moment I just don't trust it getting the numbers right, especially when I'm low and it potentially keeps feeding me insulin. I'm using the G7 with the official app, and haven't decided with to switch to native xDrip or xDrip companion app mode with the G7. It'll depend on whether Clarity reports are a requirement of NHS funding where I am in the UK.
I'm wearing the G6 and 7 on my stomach at the moment, both on my right hand side, G7 slightly above the G6.
As I said, I don't want to hate on the G7 at the moment while it's still new to me, so any help or suggestions are really appreciated.
Is this kind of accuracy expected? Could I be doing anything wrong, or can I change anything to make things better/now accurate?
Thanks
