More is better. :)  I put black and white #10 in a vise on one end and a 
drill motor on the other and twist it a lot, then let it sit overnight 
so that it will at least partially learn its new position. :)  I'd have 
to look, but I'd guess I'm getting 3-5 turns per foot, and it will vary 
from one end to the other.

Note that twisting power conductors only helps prevent coupling to and 
from those conductors.
