I think that the average PPL - if such a beast exists, is (and I generalise, again) pretty short of practice averaging a handful of hours a year, enough to satisfy the low currency requirements of the licence.
The FJ pilot has a job to do, so the actual aircraft handling is rather second nature - the trick being on target on time or winning the fight.
I was lucky enough to spend time on a FJ Sqn earlier this year, and the briefing of the sorties was where the hard work started. Operating the jet as a weapons platform, was the tricky part of the job - the actual stick/throttle/operator interface was the easy bit.
IMHO!
