Playing not overly much for two years yields some interesting stuff for me too.
It clearly shows that I started out with mindless furballing (still majority of kills in FM-2 and a lot of deaths too) but the most surprising thing is that I have a K/D of 2.5 in my favourite fighter (P-51B) but 3.5 in the P-38, a plane I rarely fly...
Killed more P-51D's then everything else, killed two 262's, one Ar-234, only ever flew one sortie and one kill in perk plane EVER (Me-262). Never shot down Spit XIV or Me-163. No kills of chutes either. Absolutely suck in N1K2, lots of kills in 'perk farmers' like F4U-1, FM-2, P-51B, La-5.
Only 8 Ostwinds killed in two years, I can't get the hang of it even now.
