"It would be awesome if in SH5; the quality of your map depended entirely on how rested and well trained your crew was -- a poorly trained bridge crew that's tired would plot an attack map that bore no relation to reality -- ships misidentified, ranges wrong, bearings wrong; and slow to update."
Yeah but during combat wouln't adrenalin kick in and make your crew focus on the task at hand?
I don't think being tired would cut it with most sub commanders for an excuse.
