2^660 is fine but 2^662 (200 digits) produces the same results as your 2^684.
Thanks RichD. If I do any more, I'll just have to manually work them. But, as I mentioned, I'm probably nearing my boundary. If ECM doesn't factor them at least into the 16x area, I'm not inclined to run GNFS at that level right now.
