I don't want to be a jackass but you need to re-evaluate your postflop game if you're really worried about results. 7k hands isn't much of a sample. Ed was dead on in his last post but there's a good chance you're making some simple and correctable postflop errors as well. Hire a coach, pick up a few more books, or just start reading and posting voraciously for a while. Get a friend who plays better than you to sweat your play while you 1-table or 2-table for a while.
And finally, don't worry about the short run so much. 7k hands isn't much of a sample.
