Shy,
I think that things may be different these days. The big point in a pilots career these days is completion of a Conversion To Type course.
Thats when flying pay, reckonable service and tour lengths are worked from.
CR is so varied and is only applicable to a specific skill set required for an Operation (Afghansitan, Libya etc) It is no longer a "one size fit all" status as a pilot.
Back in the day someone became CR.......then was always CR. Not right in my mind!
