When you have multiple EOS bodies and multiple cards shared across all the equipment, your system can provide no relevant information regarding the usage of any individual EOS body within the portfolio of cameras.
That I agree with, but if you only have one body and always format your cards after each session you will be okay. In the case where I have two different cameras, I again always start with a freshly formatted card. I know the problems associated with using multiple cards from one camera to another where the cards contain images when put in the camera.
