Barbara,
So you actually ended up shaving .3 off the dose, right? No, I don't think 1 unit is too much into a 227.
At +4 she hasn't reached nadir yet, and I think the +4 is more food related than dose related. I don't think this is a bounce. You got good action from the 1.5 this morning, and her low was right near the "green line" I am guessing, if she was at 155 and hour past then. She didn't zoom back up for PMPS, it wasn't high enough to indicate a "too high dose" this morning. Last night's increase after the shot still confuses me, but it was a one-time thing it looks like.
Do you have any idea where the original "sliding scale" that you got from Robin is? What thread it is in (so I don't have to keep asking "what's the scale say?").
