Brb: A scope is but a single tool amongst an arsenal of test equipment. While it can be a VERY useful tool, it is also quite limited in scope.
Having said that, most all of the operating design parameters of a power cord ( or any cable for that matter ) can be easily measured / observed with the right tools. It is simply a matter of correlating those measurements with how that specific cable mates in a specific interface with other components. The more consistent the operating and electrical parameters are of the mating components, the more predictable the results.
As to the info that you linked to on Shunyata's website, that does demonstrate a portion of the info that i was asking for, albeit a very small portion. Given that Shunyata claimed that most of the money spent on this very expensive product was used for R&D, posting something like that many months after the fact hardly covers the bases. That's because there are no specific figures given so that one could produce repeatable test conditions.
On top of that, those tests could be optimized to highlight specific performance traits of their units while denigrating specific performance traits of the competing unit(s). Spectral analysis over a specified bandwidth and figure specific specifications would have been FAR more valuable. Had they gone that route, the average audiophile would be lost and they wouldn't have the pretty pictures of sine waves to look at and be amazed : )
Buy and use what you like. If it makes you happy and you think that it was worth what you paid, i guess that it is money well spent. If nothing else, you'll be helping hte economy when you decide to sell and buy something else : ) Sean
