How To Choose an ETD was ... something else

a fine job.  Leaving the temperament octave is another story and the ear (at
least a skilled one) probably does a better job of blending irregularities

with use of direct interval tuning and aural techniques have proven, for me,
to be the best and fastest. >>

Greetings, 
        Why not do one's best aural tuning on a given instrument and then 
store it in the SAT?  The scaling differences, and the tuning that optimizes 
them,  between same model/makes of all the better brands of pianos are so small as 
to be undetectable without specifically looking for them, and totally off the 
radar in musical playing for 99% of listeners and performers.    And if an 
instrument is 4 cents off pitch, a well-executed tuning with a stored tuning on 
the SAT will be far closer to optimum than an aural guess in the same amount 
of time.
       The other aspect is consistancy.  It will be a rare tuner that can 
come within one cent of their previous tuning on every note!  This is important 
when overdubbing in recording situations, or when a customer wants another 
tuning exactly like the last.  Still, the unisons require the ear, hands down.  
Regards,
