stretch offset tables

[Hidetomo Katsura]

hi Don,

thanks for your response.

i guess i'm looking for that "ballpark" stretch tables so that the user 
of my tuner software can start from somewhere and customize it as 
necessary.

i'm not a piano tuner, so i don't and can't tune pianos. but the device 
in question here is my tuner software for Mac OS X.
