It it a design issue...i.e.; light gauge open links that can deform under tensile load? Or perhaps (here comes my cynical side) it's related to who ponies up the bucks to get "USAV approved".
My point is, all we have so far is "a conclusion derived, from information inferred" -" it must be true because USAV says so". In engineering circles we call that a WAG (wild-assed guess). |

I was just having fun telling you that I had absolutely no idea what you were saying, how to calculate that stuff, etc. I still think the idea of a chain stretching is
very farfetched at best... and if the guy is really worried about it, get a cheap tape measure and forget the chain. The tape measure won't get all tangled up either!
