Hey TD can you look again at the Corsair..

Very interesting! Not sure, what it means for Fw190, but Zero isn't surprising me. Its not known as a fast plane. However, this shows clearly, how much a 'feeling' can fail.

But I have a theory, what could cause this: E-bleeding
I suppose, planes are much different here. If you don't trim properly, then you bleed E all the time and this may be much more worse for a F4U than for a Zero or even Fw190. And in dogfight this is more important than max speed and pure positive acceleration.

I think, you can leave out the Ki-27 - it will not show any surprising numbers, being the weakest and slowest with its fixed gear and fixed propellar. But Ki-43 vs. A6M or Ki-84 vs. Corsair could contain some interesting results.
