I know what the marketing info says, that's not the point. Bear in mind that these are somewhat designed to justify very much higher prices. I'm looking for statistical evidence that the difference is there, not marketing colateral. They may be designed to be more reliable. And the design targets *that the manufacturer admits to* may be more stringent, but I'm interested to know what the actual measured difference is.
