One guy had 30% of his flight time as IMC(instrument). That meant 60% of his entire career was spent in IMC(two pilot operations).
Nope. You don't need to be PF to log IMC. IMC is a condition of flight. Both pilots log IMC simultaneously, just as you would day or night time.
Anyway, who cares how much IMC his logbook says he has? How did he do on the sim assessment? That's far more important than the numbers in the column.
