For what it may be worth, I have never had a rope break, except failure at the ring on initial acceleration, in over 12000 glider flights. I have had a few tug failures on both ends of the rope.

Sor of the same experience here . . in 55 years of flying gliders, I've had two rope breaks - one in rotor when a violent pitch oscillation by the towplane sent a wave down the rope that back released the CG hook on my Cirrus, and another at ca. 3000' when the towplane's defective release sent a cloud or rope heading my way. Both were non-events. And I can't remember a tow failure after airborne that we always train for, but several while still on the takeoff roll and a couple at pattern altitude or higher.
