http://folding.extremeoverclocking.com/team_summary.php?s=&t=224497I'm already down to 6th place in average ppd and dropping more. My setup isn't that much but I think will at least be consistent. A lot of my old points were earned while helping beta test the project back in Nov 2013.
As for other users that average similarly (300k pts/wu), they're likely running amazon instances. I don't think that's a great idea to do for such small % profit when most of the take ends up going to amazon. But people will do what is profitable.
