I'd be curious to see a ranking of total kills/k:d
Paging Snailman
Planes that see heavy use but still have good K/D: F4U-1A, P-47M, Yak-3, 109K, La-7, 190D9, N1K, Ki-84 and Mossie all have better K/D than Spit XVI and P-51D.
There are several statistical anomalies, which can be explained by an obscure plane used only by a few veteran players: P-38G, Ta-152, Ki-61, P-38J, P-47D11 and P-40F.
