That... is probably hardest of all. You can get 90% wins if you only play against patzers, and 90% losses if you only play against the highest-rated of all (if players in either group accept challenges with such a big rating difference). But to get 90% draws, you'd have to stay on top of things so you don't accidentally lose, yet make sure your opponent doesn't resign (unless you tell them about your ambitions, but that would be cheating).
HEY! Don't get all analytical when I'm being ironic, man :D
