Cec,
I am not an SO or FO, so no back time seat is ever logged.
My reference to the 'race' is that you seem to be so worried that others are logging time when they are not in the seat. You seem to be in a race to log your hours and think it is unfair that others are logging more flight time in the bunk than you are in total.
So are you worried that co-pilots are logging time when it is their sector as PNF; they never (usually) touch the controls/autopilot either.
