Yes indeed HAS. It was played pretty well in RAFG with the Maxeval normally being the toughest, since it was your own peers knowing how to put the pressure on. Taceval was then easier and "1's across the board" was a normal annual morale boost for Harrier force in the 70's. The USAF usually used to come down badly on NBC in particular and it was not unknown for a "National Exercise" to suddenly be announced, necessitating their withdrawal from the NATO one.
I came to the conclusion that other NATO members were somewhat baffled by the individualistic approaches of HF components and when deployed in the field we, almost literally, ran rings around the evaluators.
