Ahh, no. Preload is for the static sag, it doesn't affect the spring rate (slope of the force/distance plot). http://www.sportrider.com/tech/146_9510_tech/ explains it nicely. This assumes you haven't got progressive or variable rate springs that will coil bind as they get shorter.

Something I didn't make clear. Oil level affects the effective spring rate by changing the air gap above the oil. The air gap is effectively a progressive rate spring. By increasing the oil level, you can have a softer fork for small travel distances, to take out the small bumps, but still not bottom out under braking. Make the air gap to small and you will pop the fork seals...

There is alot of contradictions in what you have said...best you stop giving advice until you go and learn more about the subject of suspension tuning...okay
Oh, I think I have managed ok so far.
