As others have indicated it is not required by the standard. Time is money and ther should always be a benifit to what you do.
It is all just a mater of risk. Why, what and who are you doing/using the FAI for. I treat a FAI like the QA version of an engineering qualification. I like to have the ability to really know what was checked and how it was done. I usually balance the additional detail inclusion of any type into the report against what the item is -critical, tight tolerance such as a gear vrs a simple electrical box.
I personally like a lot of data but the reality is you have to balance time and such and in some cases the ONLY reason FAI is being created is because it has to be and it is really nothing more than a filled out form shoved into a file.
Things to think about
What if at some point during a calibration a year down the line you discover a tool being calibrated is received out of tolerance? Can you determine if it was used on any FAI inspection?
Your Customer gets your FAI report and verifies some dimensions and indicates that they get different readings. Would it not be nice to match your actual inspection tool deviation from nominal against their data to see if the instruments are on opposite side of the tolerance band?
