a) Ignore (from an RT point of view) the MATZ since I am 100 ft above it
Is your altimeter
really that accurate?
Or that of the possible traffic about to launch off the deck beneath you?
Is the MATZ QFE the same (in essence) as the QNH/QFE you're operating on?
The best solution is, as somebody already mentioned, drop a call to the station you're talking to, out of courtesy, to check if it's worth ringing up Marham/Waddington/Scampton et al.
It only takes about five seconds
