If you drop down to F2, a seventeenth below A440, the first coincidental
partial of that interval (the seventeenth)is A440.  That's where you
want to hear the beats, so you are actually comparing the fundamental
pitch of A440 with the fundamental of the fork, and not the second
partial which is slightly sharper in the string than in the fork.
Therefore, your A440 will be tuned a tad flat if you use F3 to check
between A440 and the fork.
