I'm not trying to be horrible, but don't confuse the sim. with reality. If those giving you marks out of ten, say X, agree with them and act accordingly. Don't enter into any debate as they have all the big cards.
As it happens in this case, a windmilling jet engine in flight should have some indictation of shaft rotation. So in this case I'd agree and people far more eloquent than myself have explained why.
