stability of pitch raises

[Farrell]

I specialize in sssssslllllooooooowwwww pitch raises. As a matter of fact, I
am an expert. Although I am ssssslllloooooowwwwwwwly losing my touch  :-).
My average pitch raise is 30 to 35 minutes. It was not that long ago that
they were all taking me 50 to 60 minutes  :-(. Even a one hour pitch raise
with proper use of an ETD (in my case the SAT) results in a very accurate
pitch raise.

Wouldn't adding additional tension to a string cause it to slowly stretch a
tad after the initial tension increase? I have always assumed that to be the
case when chipping the piano. I know it happened that way on my mother's
clothes line (he said, setting himself up).
