I am not shooting 'on' those numbers, the protocol says to shoot on the +1 number if the number is high enough to shoot, and the pre shot number is too low. What she does is rise after food then start to drop with a late nadir, sometimes at the pre shot time. What we are trying to do is keep her in good numbers most of the day. It is pretty scary because I have had low pre shot numbers but once she hits the lows and is doing so consistently then the dose is reduced. I do have a no shot number.
