You Jest..

But this is a good example IMHO of where 'anecdotal evidence' is useful!

Here we have a WWII pilot telling us how they actually used the equipment..

Which may/can be different from how the engineers intended them to use it..

Again, not enough info to say anything wrt validating a flight model

But from the WWII accounts, we know they did 'something' that seemed to improve the performance..

How much.. We don't know for sure

But as for 'how' they did it

I would be more incline to take this WWII combat pilot's accounts over some civilian pilot's interpretation of the account some 70 years after the fact
