Unless you have a solid reason to believe one (or more) lens needs calibration, why worry about it? If you consistently get images where the focus isn't where you expected it to be, you probably do have an issue. But the occasional miss is to be expected, after all, you know what you want to focus on, the camera's AF system has no idea what you want to focus on, and may choose to focus on something within the focus plane other than what you had in mind.
Here's the process I use when I suspect an issue:
AF microadjustment for the 1Ds mark III, 1D Mk3, 5D Mk2, 7D, 1D X
I've only ever had to adjust one lens-the DA 40 on my K-7.
