A 1% deficit is a very good return, on the A1c calculations, based on an average blood glucose level wouldn't you say?

Yes, Danny, a very good return indeed! I am very pleased with that kind of estimate. As an example, my GB calculated estimate A1C of 6.5% in early June, compared to an actual A1C lab testing in early June of 7.6% (which was a drop of almost 3% from my previous A1C lab testing of 10.4% in early February at which time I was finally put on insulin therapy after struggling to lower my blood glucose for almost a year on oral medications only).

When I was anticipating the results of my A1C lab test in early June, I was completely aware that it would most likely not be the 6.5% GB calculated estimate I obtained at that same time, for the precise reason I mentioned in my original post on the topic. And that is, that for the most part (probably 95% of the time) I tend to test just before eating as opposed to after eating (and Jan, I had to look up the word "postprandial" in the dictionary..lol). The only time I do a "postprandial" test, is if I have some particular interest in learning something about how what I ate affects my blood glucose or how well the insulin dosage "combated" what I ate, or something on that order.

The point is that the GB app as well as its A1C estimate calculator have been very helpful to me in working at obtaining my A1C (lab) goals. Through some additional tweaking in diet and insulin dosages and times, my next goal is an A1C lab test of 6.5% or better at my next scheduled lab test probably sometime in early October. It just requires the honesty of factoring in the reality of when the majority of testing is done to give a realistic result.

P.S. In saying how helpful the GB app has been to me, I forgot to mention just how many different programs I previously tried, (even including homemade spreadsheets requiring tons of time and effort) to effectively log my tests and be able to massage the data, in this journey to gain control of my diabetes. GB has made this all a simple process for me now. Thanks for a great app.
