if you don't consider meter variance, though.... then that would be a slightly inverse curve.
food for thought - let's just say it is a small inverse curve, and he was dropping a little at MDPS. Then you shot a .8 into a dropping BG (this is just hypothetical, not saying you did!). So that MD dose would push him down more, maybe lower than he's comfortable with. Liver panics, dumps glucose, and Cass starting doing his best Tigger impression....
Anybody think that's plausible?
