I don't think that I suggested otherwise - I said that it would give a general view and that they would need to apply their own knowledge in interpreting the information they got.........
it is worth doing if only to know it can't be done reliably......
if the Beatles had believed everything they were told about recording by Abbey Roads house engineers, some of the greatest music would never have been recorded
contextualise the question in terms of someone trying to learn and your answer should be different to "it can't be done" even if it only has a caveat saying "the results are not reliable".....
