Why still no dive acceleration difference?

[BadAim]

These aircraft are not all that much different. They are similar in size weight power and performance, it only makes sense that they perform similarly, besides a vertical dive will be measuring the effects of gravity much more than any other factor.

As for relative performance in a fight, how the pilot uses the strong points of his aircraft against the weak points of his opponent is much more important than the actual performance. I get my butt kicked by guys in inferior aircraft all the time because they are better pilots.
