Rather than continue to discuss this here - I PM'd you. In short - its a logical goal, but I don't see any less stress, expense or work comparing one method to the other.[3. IMHO. There is no correct 'method'. I see no difference between Paul's method and Humblefish's method. I have yet to hear any logical discussion as to why one method is better or worse.]
Less stress, expense and work on operator. Is that a logical goal, if the results are the same.
