SAT Pitch Raise to Lower Pitch

Thanks John. That is exactly what I do in these situations. It takes alot of
time, especially when the initial piano pitch is all over the place (kinda
kills the whole philosophy of the SAT speeding up pitch raises). In that
case you need to reset to standard pitch ('cause you don't remember the
offset because you have been setting it all over the place), measure the
pitch of your next note, mentally calculate your next target pitch :-(,
reset the offset, pitch raise that note. Like I say, when the piano is all
over the place, I tent to check my offset or pitch raise setting every few
notes. If I am headed to standard pitch, I can do that in the blink of an
eye ;-). But otherwise, is this what I am stuck with :-(?
