It doesn't do nearly as much as http://tanks.noobmeter.com/ does for World of Tanks, but I have every intention to get it there (as much as features and data available from WG permit)

For now I'd like to start the discussion on development of some sort of performance rating for WoWP - I'm open to your ideas.
Also, if you see any defects or think of any improvements for http://planes.noobmeter.com/ , please drop me a private message! Thanks!
