Obviously it has to be BCFT, Pipergirl, if only because I work there

That's a bit sharpish for all the checks on a twin, ready for an IFR flight! Including a taxi at fast walking pace (mostly between 2 and 4 minutes), run up on 2 engines (another 2 minutes once you are familiar) and checking 2 VOR/ILSs, a DME and an ADF (another 2 minutes) you are beyond 5 minutes even without taking down a clearance, waiting for traffic to land or depart ahead or doing a long list of pre-takeoff checks! I have occasionally been 25 minutes with the last 10 just waiting for clearance, although usually only because Southampton as a problem. Hence the need not to charge for that bit!
5 minutes for an air taxi pilot. 10 or 15 for an IR student or certainly an Exam callsign! Time yourself, you'll find I'm about right.
