>>How high are you willing to tune a piano, when circumstances require it? 
A-442 would be about 8 cents high, right?  I assume you would go there? 
Would you go 10 cents?  15?<<

 Greetings, 
   I would be willing to go as far as the customer wants to pay for.  A-444 
is not unheard of on the international concert stage, but I must ask, Why?  I 
do think that the bass strings may be damaged by going up 20 cents and then 
coming back down, especially if it happened several times.  Anybody have 
evidence of this?
