The outliers consistently write better prose but they never include nearly as much distinct points of information within their responses. They also have way less fluff. They include personal anecdotes. That professor probably didn't have enough materials of hers to work with.

As for checking hallucinations I definitely do not have the time to go that deep on 75 submissions a week. If that could be automated it'd be helpful. The students are correct that I can afford to spend only about 5 minutes per essay on grading (they're short, 200-250 words).
