The key here is that no one has made the claim - but it doesn't mean that
many of them don't tune by machine alone. I have gotten the impression that
some significant percentage of techs that use machines are indeed machine
tuners, and machine tuners only. With reference to the SAT, there are at
least four major ways to use the machine:

1) Measure FAC improperly, calculate a tuning, and tune each string (or one
string of each note) to what the SAT suggests.

2) Measure FAC, calculate a tuning, and tune each string (or one string of
each note) to what the SAT suggests.

3) Measure FAC, calculate a tuning, use appropriate aural tests while tuning
to make adjustments to the calculated program so that it produces a tuning
that meets with approval from your aural testing (this is what I do - I must
admit, I am at the elementary end of this approach).

4) Or use the SAT in a manual mode (with or without a calculated tuning as a
framework) where you basically do all you would normally do during an aural
tuning, but instead of aural only, you measure intervals and such with the
SAT also. I believe it is potentially a more precise way of doing what is
really like an aural-only tuning. This approach, I believe, is the most
basic description of how the Jim Colemans of the world use the SAT. This is
what I call high-level ETD/aural tuning. They use the SAT like Rembrant
(sp?) used paint. It ceases to be a machine and becomes an electronic
extension of their fingers which is wired directly to their brain.

I think that unfortunately, there are some folks that fall into category #1.
Some that use approach #2 will get a good tuning on a well-scaled piano
(but, depending on the piano scaling, is likely to be somewhere short of a
very good aural tuning) and a deficient tuning on a poor piano. I think
approach #3, when done properly, can approach or equal any good aural tuning
on a good piano. I think it can produce a good tuning on a poor piano, but
likely there will be areas (like the bass break) where a heavy dose of good
aural treatment will outpace it for sure. Done properly, approach #4 should
yield the same result on any piano that a very good aural-only tuning would
do - perhaps (arguably) better because of a potential precision benefit and
the old "two heads are better than one" philosophy.

I would like to find out how many folks fall into the various categories - I
bet if we did a survey, we would find no one in category #1 or #2!

That's my take. I could be wrong.
