It's one thing to learn the basic operations of a station, a whole other to be an expert in a discipline.
Seriously? This week Rand will be the expert in penology, next week she'll have a degree in Ion propulsion and the week after that she'll be an expert in alien languages.![]()
Dunno, worked for Spock... and Neelix... and Dax...
But again, that's projecting the story as is onto Rand as is. It's not as if Noel's so-called expertise affected the story in any way, any more than Ann Mulhall's qualification in astrobiology helped her while possessed by an alien, or McGiver's historical qualifications had any relevance to her ability to help Khan take over the ship.
The question was whether Rand could have operated the machine safely. If she was established to have sufficient technical skills, the answer would be yes. She does not need to be an expert within the confines of that story.
