The alien Russ pulled broke at 900lbs. Were you able to generate 4KN with your bounce test? Chris from BD said he was able to generate 1000lbs doing some serious bouncing with several inches of free-fall; I don't think I was able to generate that much force in my bounce tests.
The aliens that failed in the field all failed with body weight or small falls... maybe a bounce test would have helped, maybe not. The loop swage failure certainly would have been detected.

Again, completely unscientific testing. I was lifting myself by jumping about a foot up with the slings on my feet stopping all downward force each time. Looked pretty funny, I'm sure. I'm feeling good about greeny now and hope that is the worst test it ever gets.
Using a screamer, I discovered that I was unable to generate over 2kN of force by bouncing. Of course, I'm a pipsqueak, at 150#, so perhaps you can do better than that. Anyway, that's why I wound up doing the testing I did (described above).
