[pianotech] Pitch raise criteria

[Rob McCall]

Bruce, et al,

Is this a common shortcut?  Leaving off the copper-wound and the top  
octave on raises less than a certain value (in this case, 10 cents)?  
That would definitely be a time saver as long as it didn't sacrifice  
the stability of the final tuning. I'm assuming you get good results,  
Bruce?

Or maybe I'm reading it differently... Do you make this first pass on  
the middle sections as a precursor to your tuning when a pitch raise  
isn't needed?

Thanks,

Rob
