I think, Holger, that you present some very real concerns and very real issues that could arise from pumping. As a pumper, however, I think you present the potential issues in a way that sounds like they will be problems at some point. I don’t think that’s either ironic or sarcastic. I think it’s just negative and not really representative of what will happen if somebody switches over to the pump.
For me, the pump change highs were a huuuuuge concern and I think you hit the nail on the head with your calculations on what could have been a major issue had it turned out to be the case. The absolute truth is, however, that in approximately 40 pump changes, so far, I’ve had maybe 5 total pump change highs and I can attribute 4 of those to the site I chose. That doen’t even mean that I have to avoid those sites in the future. It just means that, through experience, I’m better able to anticipate and deal with potential pump change issues before they become a problem.
So, yeah, you are absolutely right in presenting potential issues but, as with all things diabetic, YMMV.
