Yes, but the bottom line is that when the oboist goes looking for 
A440, they'll look for it at A4(1). Your 2:1 octave will install A440 
on A3(2). However if when you move up into the treble with your 
octaves, the octave you're laying down is something other than a 2:1, 
A4(1) will be pushed sharp of the reference A440. Oboists and 
flautists notice that kind of thing.

That's why, when I move from the initial A4 to the next-step A3, I do 
it with the octave I know I'm going to use at the beginning of the 
march up through the treble: a 3:1 octave. If A440 moves, it's 
because of the board.

Then again if your using an ETD, you can tune into the weather 
channel for the 45 seconds it takes to execute the spreadsheet.  <g>
