They presumably record the behaviour of the person flying the simulator though during the simulated emergency (or any situation). What I'm suggesting is that a report is generated from recorded data to show that the pilot didn't do what was necessarily expected - turning off the in-flight entertainment is an example which might be judged an odd but innocuous action, but turning off the engines, or hammering 50 buttons in the space of a minute, or something, would indicate behaviour that is well outside of the expected parameters. That should be flagged.

If the other flight crew in the simulator at the same time can tell that the pilot was behaving erratically then the simulator reporting software should be able to tell as well.
