for rear preload, it should be set so that you are at 1/3 the suspension travel with the load. this should put the bike geometry's at the design point.
If you set it too soft there is greater potential to get headshake,
because the fork angle is too low.
it also is not exact, I don't reset mine every time I change what I am carryiing.
