If you look at the crew list in Commander, it includes you right at the top with every available qualification.
But I don't know if Commander does that on its own, or if its reading something that's already in the game and factors into gameplay.
If it's the latter, and it does factor in, does it mean that when you are in a particular station doing some "job" yourself, the efficiency for that compartment increases accordingly? Obviously you can't look at the bar to see what happens, because you'd have to leave the station to do it.
I do know that people say you can hear stuff on the 'phones if you take over that station that the sonar man can't hear...
OTOH, the performance of my flak gun station is definitely NOT improved when I take over the gun from my flak gunner.
