justified RAF claims vs hard kills

[kettbo]

I've not read up on the RAF since high school. I have seen a few threads about over-claiming on both sides for the Axis and Allied fence. I am re-reading Caldwell's JG26 War Diary Part 1. There are many references to the impressive over claiming by the RAF. With all the modern research tools, has there been a justification made using real loss records, something like Caldwell? I know the British had intercepts so at least at the top they knew that 40 claims might mean 10-15 real victories? Who was claiming all these victories? Particular units? Individuals? Any official repercussion for over-claiming? Any anecdotes of hushed-up admonishment/punishment? Is there a list with claimed kills and what the probable real tally might be?

Again, I know victories never matched claims in any air force. I was shocked by what I read in JG26 book
