Although I agree with much of what youve written there is a clear diffrence between Allied losses, say in 1944 and German losses in 1940.
In some of the links I posted its very clear that the Germans couldnt afford the loss rate while the RAF could. The problem for the RAF was pilots and it was a good thing they were fighting over friendly skies.
Its not just about men and machines though as the BoB was won as much by British technical innovation as by them. Radar played a part, but so did the Observer Corps, this enabled the limited fighter resources to be employed at just the right time and place. The introduction of the sector stations to filter the information and give the commanders a much more accurrate picture of events than any german commander received was another bonus. Something the Germans did themselves later in the war.
The Germans also did themselves no favours by continually changing their goalposts.
