Pongo:
You mention the Warts! That's what I'm getting at in the top post. Where is that stuff - the lateral control problems in dives and the power loss when bunting?
The other stuff:
IMHO the Kanalgeschwader pilots had an advantage in experience and tactics that was hard to beat. The RAF had good results defending their own land in 1940, but fighting over neutral ground or enemy territory is a different ballgame. I think there was a real learning curve.
Along with the lack of "warts" in this game, we have the fact that different aircraft attributes were important for success in real life than are important for success in our arena.
Top speed is much more important than turn rate in real life. Look at the USN vs. Japan if you doubt that.
Many if not most kills were achieved by surprise, sneaking up on the enemy. In a Fw 190 vs. Spitfire Mk. V, you can cruise with almost no fear. Even if a Spitfire spots you and you don't spot him, he will not be able to catch you unless he has a large altitude advantage. If the Fw 190 spots the Spitfire V first, he can close for the attack even if he initially lower or slower.
In here that advantage is meaningless. Only a blind Spit pilot can miss the giant neon billboard which announces the approach of the Fw.
Also here's my response to your personal stats.

funkedup has 38 kills and has been killed 8 times in the Spitfire Mk IX.
funkedup has 13 kills and has been killed 3 times in the Fw 190A-8.
P.S. You seem to be a pretty good Spit pilot, want to join my squad?
