[CAUT] huge pitch raise question

[Cy Shuster]

Pianos that need huge pitch raises are grossly under-maintained.  This is 
probably the most significant factor in string breakage.

I do as much as a semitone in one pass, A0-C8.  I've tried tippy-toeing by 
bringing up all the C's, then the A's, and so on, and unless the piano has 
some serious damage, it seems a waste of time.

On the second pass, it's close enough to use the pitch raise feature of your 
favorite ETD (TuneLab for me, with the "Measure every note" option).
