You're correct. Don't forget, that when I look at e-mail, it's only 7 AM where I live. So my mind just isn't working at full capasity yet.

 Wim,
 Check your math! 6 cents FLAT of A-440 would be roughly 438.5 cps. (if
 it was PLUS 6 cents it would be 441.5 cps).

     An A fork that is 6 cents low is not at A432. At A, there are four
     cents per beat. So a fork that is 6 cents flat is at A442.5. It
     shouldn't take much to file throat of the fork to reach 440.

 prime example of minutiae over basics. The math doesn't matter a whit 
hen you're changing the pitch of a tuning fork, but filing in the right 
lace does. Unless I'm in the wrong universe, to raise pitch you file 
he tine tips, not the throat.
