Since we know that most, if any falls don't produce the kind of KN force generated by the x2 lab drop test, and 10KN+ gear isn't exaclty breaking left and right... etc etc
Are there any studies or data out there regarding what range of KNs are typically generated in more real world falls (not necessarily factor 2).
John Long cites scientist Craig Connally in his book who throws out a 5.5-8.5 KN max figure. JL also mentions that in an eight year period QA at Black Diamond hadn't seen any stopper over 10KN fail and only a few 10KN carabiners fail in closed gate mode.
I guess if some yates screamers kick in at 2KN, we know we can get into that range probably without trying too hard :-D
I can't recall of hearing of any 5KN type gear breaking, I hear of Micros breaking but I don't know how low they were rated.
Anyway, just curious, be nice to know what's a little more based in the real world when you're forced / choose to start placing pro that's dropping into the lower KNs
