Although I did know the answers to your questions and I stick by every word of them - and you actually proved to the "CAA Examiner" that you were NOT fully prepared for either of the flight tests that you went to do (and I believe that to be the fault of your training provider, not you [at least, not 'directly'] - I have never held a European CPL (just an FAA one). I've often thought of applying for one of the JAA ones but never got round to it (but that is an 'aside' that doesn't really have any bearing on this discussion).
What I would really like to ask is did your "CAA Examiner" ask you "Why you had elected to use the JAA figures and not the CAA ones?" or "Where would you find the correct answer?"
I'd be equally interested (for professional reasons) to hear which school it was and/or which "CAA Examiner" it was - maybe you would send me a PM with the answers?
