>>Hi Jon,
>>In my opinion, the problem with that scenario is that as the piano passes 
>>through A-440 not all of the piano moves the same.  In the mid west where 
>>humidity changes are great, the middle 2/3's moves the most so though the 
>>pitch changes through the season the middle moves more than the ends..  I 
>>have found the only time the piano is at whatever pitch you tune it is when 
>>you are finished, not several weeks after.
