Basically straight rate spring compresses at say 5.2kg/mm ... so it takes 5.2kgs to compress the spring one mm. Adding preload just increases the amount of weight/force before the spring compresses further.. put a big load of weight onto it and it'll overcome the preload and continue.
Damping also influences where in the stroke the shock rides.
That's why a heavier spring with less preload can feel plusher in the initial action. You don't need to overcome the preload to set it in action. The problem being too heavy is usually when you are hitting something after already being half way through the stroke. The sometimes she gets a bit too firm instead of using the travel up.
