BADRT,
Yup, I remember it all well, and not just in CX.
Was having some difficulty on a conversion and mentioned the very points you make to my new (and excellent) trainer. He said "Well, just fly the jet and I'll say nothing unless you're about to kill us all."
Two days later he said "Can't see what the problem was." Thanks Pete
Another, much less problematic was that, on a command course, as each successive TC told me to alter my briefing and I incorporated his words of wisdom, the next would come up with different advice. Mentioned this and the trainer just said "OK, no more comments on your briefings!" Sorted!
Neither of the foregoing was in CX.
