Last tour (through July), I flew one sortie in Attack Mode, got one kill in a Stuka, and somehow earned ranked 1 in attack. Inb4 score doesn't matter. Just a bug, reporting it is all.
Edit: score page is correct however...in game it was listed as rank 1 and overall went from 1900-something to 800-something and I could take control of CVs over those technically ranked better than me.
