We test this size of cam five times and got the maxium load rate shown in the table below.

This line doesn't exactly make me want to go out and take some whippers on their gear.

They most likely mean they took five samples and pulled them to destruction and recorded their failing strengths. They then took the average or lowest value of those tests and rounded down to the nearest number and stamped that value as the listed breaking strength on their cams. Three Sigma is a much more reliable rating standard and five test samples is not near enough, but we are not dealing with Black Diamond here.

Anyway, I doubt they pull each cam to its average breaking strength then sell them. They would be warped to hell, unsafe and useless if they did that.
