GBA1c calculator numbers

On the calculator it gives me an average BG of141.4, but on my iphone app it gives me 144. Why the difference using the same data. This is using 179 tests.

Check the 90 day web graph for the average. This is the figure used to calculate the A1c. The average on the portable device "App" is an average of all blood glucose data input to date.

I'd like to know what formula is used to calculate the GBA1c. I showed my diabetes doctor the site yeasterday and we looked at my numbers and the last measurements IRL. My test said 40, GBA1c on this site says 32.7.

There is according to my doctor a few ways to calculate the average GBA1c, so how is it done on this site?

Thx for the info Dano. By following the threads I found the ADAG 2007 formula. It has a couple of years on it's back and I'm not sure if we have a newer one as we "used to" measure AC1 in a different way then the US.
