Oh, well, so much for that "YMMV", eh?

And I'll contend that "theories / phenomena / etc." need to be put to the
double blind test before I'll bite. Even at that, I'll contend that my
"flavor" of diabetes is different than my neighbor's and probably always
will be. My diabetes has always looked "logic" and "math" in the face and
laughed heartily <vbg>

As for bg/carb insulin/carb bg/insulin ratios "forbidding" anything, or
"dictating" anything, that's the "magic" formula they're looking for to
close the loop. I bet they never realized it was this simple <vbg>

Every doc I've ever worked with has expressed the feeling that they wished
it was all easily pigeon holed and relegated to categories. "If A happens,
do B". Ahh, if it were that simple :-)

I don't argue the basic fact that there are variables that come into play
here, but variables are just that - variables. For me, life is one of the
biggest - every day is slightly different. Even if I do exactly the same
things, eat the same food, sleep the same hours, I'm another day older (not
necessarily wiser).

It's an interesting experiment, but let's remember it's just that.
