post pitch-raise creep?

[Andrew and Rebeca Anderson]

I find I have to modify the overpull target percentages to fit the 
piano I am working on.  Little pianos (upright) don't seem to like 
much overpull.  Concert grands on the other hand want a whole lot of 
overpull.  Typically I find that 10 - 18 % works well on the bass 
bridge, wound wire and 20 -28 % works well in the tenor and lower 
treble.   Generally switch to 30 - 38% in the high treble, especially 
after the dampers stop.  Verituner BTW
