[pianotech] tuning "disclaimer" after large pitch raise?

[David Nereson]

     I seem to remember one of the old PTG brochures about piano 
care saying a tuning can't be expected to be as stable after a 
big pitch raise as it would be if had already been close to 
pitch.
    If this is true (and I tend to think it is), then one 
shouldn't feel guilty if the tuning slips a little, and to avoid 
immediate call-backs, do any of you include a "disclaimer" after 
a large pitch raise (say, more than 50cents)?
    I remember one of our esteemed colleagues at one of the 
national conventions saying he would not charge for a fine 
tuning if the piano was drastically flat.  He would pitch raise 
it, do a "decent" tuning, then insist on coming back for the 
fine tuning after a few weeks so the owner could play the heck 
out of it for a while, allowing the strings and board to do 
their slipping and settling.
