Personally I think it would be easy to distinguish Pear Anjou from Monster in a high resolution setup (the Anjou's have ultra low inductance numbers while keeping capacitance in check).
Then why do you think John Atkinson and Dave Clark do not take up the challenge?
If it is "easy to distinguish" then surely the time/effort would be worth a million bucks?
I mean these people do audio listening tests and measurements for a living...it should be a simple matter for a respected & highly discerning reviewer.
After all, the challenge is not about "inductance" or other measurable differences - it appears to be about the ability to demonstrate being able to hear better performance; simply to support the claims, made with ease, in the reviewers articles, which are published in the media and influence a great many buyers. That is the jist of it in the way I understand it. I don't see a trick or impossible challenge as you do. I mean what is impossible about something that can be done with ease?
