But, we are digressing here. No amount of calibration can overcome the proud papa phactor.

Not arbitrary. The units are sent in for calibration according the manufacturer's recommended schedule, department policy (which may be more frequent) and the law. Tuning forks are used to check the accuracy of the radar between calibrations (the forks also go in with the unit to verify their accuracy .. at least thats what we did .. can't speak for others.)
