Yes ..... though It was more in the way of assessing new or different kit....

but I do agree ......"there's more in heaven and earth" etc, than just science and specifications. i also rather like this quote

"Round about the accredited and orderly facts of every science there ever floats a sort of dust-cloud of exceptional observations, of occurrences minute and irregular and seldom met with, which it always proves more easy to ignore than to attend to... Anyone will renovate his science who will steadily look after the irregular phenomena, and when science is renewed, its new formulas often have more of the voice of the exceptions in them than of what were supposed to be the rules."

    - William James

I'm a big believer in some of the more alternative "energies" even though I have been involved with conventional science wisdom for my whole life. I have manipulated the "beach ball" in Tai chi,  I also dowse, both of which need breathing control  and a centering [grounding] of the self  to be effective.  Though I think some of this may be too much for the more vociferous naysayers that inhabit the darker areas of this forum!
