My endo occasionally downloads pump, maybe 1/year. Sometimes asks questions. Almost always download BG meter, loves to circle the lows !. But we don't really discuss detailed, day to day (hour by hour)logs or adjustments that I do, just general update on how things are going, and if there are any specific things I want to discuss.
I was on the pump for many years before going to my current endo, and I usually don't consult with them for changes. But I think for those new to pump, or seeking help from their endo/health care team, it's a great thing to do. But there can also be a tendency to focus more on the numbers, and less on the PERSON. Each person is different and needs to find what works best for them.
For those with Minimed, some doctors can use a different version of software, not Carelink, which provides additional reports. One time my endo printed out a 'compliance' report, showing how often certain things were done, such as rewind/prime.
