newbie questions: stretching

When it comes to many of those pianos there is no acceptable
compromise.  If you use one standard it sound horrible and if you use
another standard it sound terrible.  You are caught between a rock and
a hard place.  You do what you can and hope the customer is so used to
the piano they don't notice.

That being said, yes the bass is stretched downward and there are the
following tests to evaluate for a best solution.

First the fifth (lower note to a fifth above) should be as pure as you
can make it.  

Listen to the octave and to the double octave when you have it.

Comparing the minor third to the invert major sixth the major third
should be slower be about one beat per second.  Example: C2 - D#2 and
D#2 - C3.  The difference reflects the degree of stretch.

Decreasing sixth or tenths help find notes that need to be checked or
compromised.

Listen to the octaves.

EDTs can only tell part of the story, the ears can detect the whole
story when educated.
