In general, I would say any meeting, with anyone where you dump a bunch of data on them and expect an instant analysis is a set up for failure.
I never bring data with me to an endo appointment unless I can send it beforehand, and unless there is going to be adequate time to discuss the data. I might add that neither of these have ever happened, so my endo appointments are essentially data free zones (except for report on an A1c, if I have had one close to the appointment).
Regardless, for virtually every appointment, I bring a written list of what I would like to accomplish and I discuss that first thing to get agreement. I don't leave until I have checked off the items on the list.
IMO, if your endo is beating you up for "bad" numbers, as opposed to saying things like, "Your A1C seems high (or extremely high, or higher than last time, etc), what do you think is causing that?" Or, "do you think we should try tweaking (basal/bolus/timing/etc)?", then you might want to look for a different endo.
