Bose-x,
I agree fully with regard to para dropping not coming under IFR (same as the aerial survey work I did).
Disagree over the logging of IFR time as being pointless though! If you want to become an Instrument Rating Instructor (for example) the minimum requirements are to "Have completed at least 800 hours of flight time under IFR of which at least 400 shall be in aeroplanes. Where pilots have recorded flight by sole reference to instruments and not under IFR, then 1 hour sole reference to instruments may be counted as 4 hours flight by IFR."
So yes, you are right, even without being in IMC you can still qualify as an IRI based on your IFR experience........so can be worth recording depending on what your career plans are really.
Whether you agree with Guppy or the CAA is entirely up to you.
Happy flying
