Hi Dan,
As a professional researcher (low level as far as the Luftwaffe), I think you need to expand your field of view. I think I know what you're trying to do, but an issue like this needs to be looked at from many angles.

Based on my research, the reason the war was won was sheer strength of numbers on the Allied side. And it wasn't just the air arm but ground troops, armor, artillery, etc. I encourage you to keep at it. Perseverance is the first thing.
Usual disclaimer,
