What's the logic for not filling up damage control? I have filled it up prior to my patrol.

While on the subject of crew management.. after filling up my damage team with zero renown recruits I notice during the patrol they get an up arrow saying they've been promoted. They're no longer called recruits but are given another title. They seem to get specialties assigned (some become quite good!) When I get back to port I have a few promotions listed but when I drag them across the screen I get a message saying nobody has been promoted so I can't continue.. Does anyone know what that means?

Also, is the experience they gain a factor of time, or do practise dives, getting shot at, etc.. increase the experience? Finally.. does the experience get them promoted , or increase their skills, or do something else? I'm not sure what's going on but it seems like there's something happening that would be fun to understand.
