Well, I remember that c' is middle C, and that A440 is in the octave
above it, so it is a', and so \relative f' should work fine if I
remember that \relative f' is the incantation for getting the ' octave.
In contrast, doing an arithmetic mean on the frequency is not exactly
the most natural operation for me, and since to the mind of \relative,
feses is above eisis, frequencies are not a reliable indicator for
proximity anyway.

The interesting question is whether \relative c' gives you (namely
Graham Percival) a _better_ idea of what the next note will be rather
than, say, \relative a'.
Reading \relative means getting a grasp for relative distances from one
note to the next, anyway. The question is what to base the starting
note on. I see two distinctive starting points for starting with x???
\relative x??? { x
Namely start with the starting pitch.
\relative f??? { x
Namely start with the starting octave.
For violin players, \relative c' covers nothing below the G-string
(short of accidentals). But that kind of reasoning does not sound
PG-13.
