Tmarsh, respectfully, you've got it completely wrong. 1/ Your 'guy' spun you a line or you misunderstood him. 2/ Other manufacturers have only started talking about 3-Sigma because they are frustrated that it has been misrepresented or mistaken as meaing something unique or special & so they've decided to say "me-too, look I've got 3-Sigma". 3/ There is no 3-Sigma test, there is no 3-Sigma certification, it's just a shorthand way of expressing one way of setting your ratings lower than the mean test results. You work it out with a calculator. It costs nothing. The actual testing is the same irrespective of what you want to use as a safety factor - nothing, 1-Sigma, 3-Sigma, 7-Sigma, -33%, whatever. And no responsible climbing equipment manufacturer uses Mean test results for their rating. Promoting "3-Sigma" as something special is just marketing fluff.

You must be taking the piss with your comment "would you rather the 99.87% or 50% rating when you have a small nut close to its rated strength in a fall"? Either way I'm out of it.
