ETD's accurate?

        Um, does "slop in" used here refer to a 1 cent tolerance? The same 1 
cent accepted by the Guild testing procedures?  In other words, are you 
saying that a good tuning becomes a sloppy tuning if it varies by one cent? 
       Also Richard, are you saying you can tune the same piano, with say, 
tunings a week apart, aurally, and have all 88 notes the same on both 
tunings, within less than 1 cent?  I have never seen this happen.  Especially 
when you consider the temperature change of a degree or two will render all 
this 1 cent precision an academic measurement.
