No need to apologize.... I know this has diverged a bit from my original intent, which was as a follow-up to my contemplating switching to Apidra (see that discussion here). If you'd like to start a new discussion about how various insulins work in pumps (you might get a broader audience if you do), you are free to do that, but I don't mind the discussion here.
But if you haven't seen the other discussion I linked to, take a look at that. I learned A LOT from that one.
