Using an ETD to hone aural skills

I've been doing this every day since October (as I'm learning to set a =
temperament), and it was a help until I got down within about a cent.  =
Then I started disagreeing with TuneLab, and rechecking drove me crazy.  =
(It's extrapolating iH based on just a few measurements, after all.)  I =
also found that different treble octave settings could change the target =
frequencies in the temperament by around a cent (even after readjusting =
the deviation curve).

By the way, TuneLab has extensive support for the RPT Exam, and can =
automatically score it.  There's a separate document for these features =
at www.tunelab-world.com.

  Comment ... or maybe more of a question.

  In doing this, we are using the ETD as the final judge, the standard =
if you will. Yet for the RPT exam, the standard is set aurally.

  So, it seems to me, that when you are "off" by a few 10ths of a cent =
(or even more) you may actually be "on" to a better placement of that =
note than the machine has calculated.

  I'd be interested in others' comments, including those of you who are =
examiners. And -- related -- how far different can an ETD calculated =
tuning be from a good aurally done exam tuning in your experience.
