I'm a mathematician by the education so viewing the data just clicks in my brain
Hi, Breck, I'm using xDrip+ too, not with G5, with libre on script and a MiaoMiao transmitter.
In the xDrip+ statistics page, there's a couple of metrics, GVI and PGS, which may appeal to your math skills.
I've not been able to find much on the internet about how to interpret them, so they might be things which just haven't caught on in the real world.
The GVI is straight-forward enough - how short is the line between two points in time, reflecting the amount of deviation - and PGS range seems to between 4.6 for non-diabetics and 40 for wayward control, reflecting variability, mean glucose, time in range and hypo events as a single number.
I found this article at link below, but more or less gave up when it explained that the TIR function is, "a decreasing rectangular hyperbolic equation which asymptotes at a maximum value at 20% time in range"!
I'm not sure how to interpret PGS. It seems to be offered as a complement to a1c. I don't know whether I should assess the number on a weekly, monthly or 90 day basis. I don't know whether docs are at all familiar with it.
Any views on how to read and make use the PGS number would be gratefully received.
