IMHO air gunners are a different breed. And I remember that even in late 60s it was generally well known that 8th AF air gunners' claims were highly inflated. And at least from 1969 it was clear that even during the BoB RAF claims were inflated. And at least in 70s it became clear that the RAF claims over France in 1941 were at least at times highly inflated. The difference is that this is given as general info and not so that someone goes through certain aces claims and compared them to surviving German loss records.

On the other hand there are still authors who tried to show that claims of certain German aces are 100% accurate. E.g. the are some rather desperate attemps to make Marseille's claims 100% accurate in Heaton's & Lewis' Marseille book.
