To use FAA definitions to meet FAA requirements?

Then use Company A's definitions to meet Company A's requirements? And Company B's definitions to meet Company B's requirements? And Company C's definitions...?

There are so many discussions in which the advice - "log for the airlines, not the FAA" is given. Is this like the only industry where people say "don't collect the data to begin with" instead of "collect the data and then present it in the way a potential employer wants"?

Really, I've never heard a group of accountants say, "No. Don't ever work at McD's as a teenager because when you are applying for a job as an accountant, they won't think it's good experience."
