Is a 2% difference between the top plane and any of the next 3 planes "statistically significant"?
Actually, it is significant given the distribution. But only in a statistical sense. For all intents and purposes, the F4u-1C, La-7 and Spit-IX are being used about the same against fighters. The F4u-1C just has a better k/d. The Dora is being used slightly less, but has as good of a k/d as the 1C. Basically, the 1C and Dora are performing similarly, only more people prefer the 1C. I'd tend to think that was because of overall diversity and familiarity and not necessarily performance based.
An interesting trend... the Dora used to have a much better k/d than the CHog for the first two weeks it was around. It was nearly 1.5 k/d vs fighters as compared to the CHog that was at 1.23 k/d vs fighters during the same two weeks. As the dora novelty wore off and people returned to their favorite rides leaving only the dedicated LW pilots to the dora... the dora's k/d went down and the F4u-1Cs went up. Pretty hard to support the "LW planes only do good because of the pilots" argument with those stats.
But then.. I fly the Yak-9U.. so what do I care. None of the top 4 are an insurmountable challenge to it.. and thusly, I don't think any of them should be perked.
