cleeds,
Well, any test of any validity has to be reproducible. Which would make it into conducting another ("clone") test. Some tests are too complicated for many people to make them. Not necessarily these audio tests, but in other fields.
Now, what you are saying is accounting for variables. That is the tricky part for any test/experiment that a person does in any field. With careful design and method selection, it can be reasonably achieved. If the room will influence the cable, result is worthless as the test has not been designed sufficiently well. That is one of the reasons to read methods before reading article as a whole.
