This won't be much help to you probably but I never switch memory cards from camera to camera, and I've never reformatted any memory card so I just go by the file number on the memory card for a particular camera. For example, the last image I shot using my a7rIV is DSC00949.ARW so I'm assuming I've taken 949 images with this camera so far.
I've never found any of the shutter count sites I've tried to be very accurate.
Do shutter counts include electronic shutter as well as mechanical? I think my image count method includes both methods of making an exposure on my cameras.
Yes, I remove and format after an outing. The other questions I can't answer. The app in German worked well at one time but now won't let me do anything. The link showed 137 clicks on the a9 and I know better than that since I can do more than that in a backyard afternoon.
