Hehe, I can assure you it is more like 2k+ runs but have only logged around 700 so I didn't want to overestimate. Too bad the prices have dropped so low that it is hardly worth the effort any more. :( Like I said, though, this is EXTREMELY rare. If you were try to get this on purpose I would say that you have a better chance of a chain from dusties. I just wish I knew what caused it. It would be pretty interesting.
