Hi
@charlie000 ,
I don't claim to be a great maffmagician....
It may all hinge on how accurate your meter is for starters? I also test upto 10-12 times a day. Even though I occasionally use a Libre..
However, I use an Accu-Check Mobile meter that gets checked when possible against a calibrated NHS "standard issue" device when ever they use theirs on me. I take a second with mine.. Mine reads 15% higher.. Not exactly done in a lab with too many "variables," I know..
So then I log them on a Diaconnect app. (Simply because it works across two different OS with an Android phone & an IPad?
The A1c calculation romps in 15% higher than the lab result too...
This is where it gets interesting regarding your specific query? Regarding the MySugr app you use.
I also have this app on my Android phone (Galaxy A3.) which hasn't been used in a while due to my preference to the aformentioned Diaconnect app, I have a Bluetooth adaptor on my meter which I can send all the data to the MySugr app. (Which only works with MySugr.)
MySugr has interestingly calculated the same data from the meter approximately 3.5% lower than the Diaconnect app. Basically taking the same data & giving a different answer...
My observations may help or mix it up further..
Personally, I would structure more daily tests than you currently do. & compare the app result to a couple of A1c lab results back from the doc first?
