As indicated above, the variation from individual to individual is wide. And the number by itself isn’t good or bad. This isn’t like a lab test where there is a reference range and you’re okay within it and in trouble outside it. Your ratios are just your ratios; they correspond to the complex system that is your own unique physiology. Aside from that they have no particular meaning.
Mine are as follows:
Regular
AM 1:8
PM 1:11
Apidra or Novolog
AM 1:12
PM 1:16
The one part of your story that bothers me just a tad is this:
I, too, would like to know how he/she arrived at those numbers. Were they plucked out of the air? Lifted from some one-size-fits-all chart in a textbook? I know of no way to determine them safely and accurately other than through empirical testing; If there’s another method, I would be very grateful to learn what it is.
