Overpull

Well, I think it is safe to assume that it is not possible to do a pitch
correction with one pass and expect concert level standards. But for a
normal correction of pitch, nothing too wild, accuracy within in one cent
would be great!

You are right, 'pitch correction' is a much better description of what is
actually happening. I'll try and use that from now on.

Sure, that sounds really good. But my experience seems to be that after the
correction as occurred, each note varies to a certain degree. I just wonder
if corrections can be more controlled?

Here is a specific question: is there a difference in overpull when a string
is 10 cents vs. 12 cents flat? And how do the surrounding strings effect the
amount of overpull necessary for that specific string?

This is just a simplified example:
A2  A#2  B2  C3
-10  -13   -9   -12 (from where they should be)

Do the current locations effect the amount of overpull for each note?
