One can go through a 20bi downswing while playing well through it. The same goes for a 30bi downswing although I think the latter is v v rare. 30bi swings down are normal if you are running bad and playing bad at the same time. I've done it a couple times at hsnl it was pretty easy to do. My worst was -40 buy ins at 10/20nl on Party but I was usually the worst player at the table during this time while surrounded by lolo, newb1e, buddy, bld, etc.
