Pulling out of a sideways swing?

Here is my graph of about 80K hands, the run to date. The graph shows running BBs won. As you can see, I am potentially pulling out of a sideways run. If it sticks, it will be on the order of 50K hands and 1000 BBs. Leatherass, on the stoxpoker site, posted his first 1M hands at high stakes, and showed a 100K 30 buyin sideswing, so I suppose this make mine half-assed.
