Its usage doesn't support that, save.
It is natural, given the nature of the MA, to see the most capable version of an airframe dominate the usage of that airframe. It is true of A6Ms, Bf109s, Bf110s, Hurricanes, P-47s, P-51s and Spitfires. The Fw190A-8 was an anomaly produced by its high ENY rating and when that changed the anomaly receded. The F4U-1A is the best free version for air-to-air and the F4U-1D is the best free version for air-to-mud and that prevents a single F4U from dominating F4U airframe use. The P-38J seems to be the chosen mount for many of the most fanatical P-38 fans for reasons not associated with ENY or, I suspect, the game and that distorts those numbers.
Keep in mind that my ride is also pretty much just screwed against a non-incompetent in a Yak-3 as well, and I don't have a newer version to switch to. I'll grant you I rarely play nowadays so it doesn't actually affect me that much.
