With respect to combat reports, you also have to take into account the fact that nobody is thinking straight in the heat of the moment, that memory is relative, reports are made by humans, and therefore no combat report can ever be 100% accurate. If it is a report of a kill we will most likely never get the other side of the story.

Bingo!

Which is why FM are and should be based of real world 'test' data

In that test reports don't rely on the pilot to remember the speed, angle, throttle setting, manafold pressure, etc per min

The engineers installed recording devices on the plane to record such things

Than and now

Just because than and now humans make teriable recording devices

10 people witness a crime and afterwords the cops ask them what the guy looked like and they get 10 different discritpions

Now imagine trying to remember what you speed was while you were trying to out turn a 109 in a turn fight!
