You would choose the number to which the magnetic variation is taking
the runway. For example around the western US you would choose the
higher number as if you don't you'll have to renumber the runway that
much sooner.

What??? You don't rename a runway after it has been named.

The reg has been quoted. Show me where it says you have to take the
movement of magnetic variation into account.
