It is really simple. If you don't hear anything to correct, don't
correct it.
Of course, but the usual test is to more easily hear what might go wrong
when there *is* something to correct.
As Scott has pointed out though, it's not a hands off process, but one that
definitely requires listening and tuning, so you are right in that testing
on known good material is probably pointless in this case.
