stability of pitch raises (Ron's question)

[jolly roger]

An interesting addendum to Ron's questions,  Since many of you charge extra
for pitch raises, does any one charge more yet again for large pitch
lowerings,  Well many pianos are a real wrestling match in the opposite
direction.
Not often do I charge for raising, but I offer the customer the choice,
when a piano is sharp at this time of year.  Tune to A442 for example or
pay for lowering, to A440.   Most times the piano gets tuned sharp.
