PR: Double-Unders

My personal record for consecutive double-unders was set a few months ago:  67.  I've gotten halfway reliable at doing sets of 50, by which I mean I can do them about half the time;  50 is about as many as I expect to need to do in a WOD.  Perhaps I'll see if I can get to 100 in a row.  I don't think I'll try to go beyond that.
