[pianotech] How come?

[Thomas Cole]

Have you considered that it may be a function of pin setting technique? 
In my own experience if I set the pins too heavily in the high treble, 
those notes will be sharp at the next tuning. Most people don't pound 
the high treble so I try to set the pins more lightly.
