Proportion of winning/losing players

I've been wondering what proportion of players in each limit fall into each category. If I had more poker tracker players in my database I might be able to draw some conclusions, but I was wondering if anyone out there had any either anecdotal thoughts or empirical data:

1) people who seem to be trying to lose as quickly as possible
2) steadily losing players
3) players who would be breakeven, but lose to the rake
4) players who are breakeven after the rake
5) players who make steady returns
6) players who make a killing
