Fork Preload

Hi Guys,.....Was reading an article on another website about fork spring preload. It claimed that preload only effects the first inch of travel. This is going to be harder to type then actually ask! Using easy numbers just for example, If you had a 20 pound rated straight rate spring and compress it 1 inch, you would get 20 pounds, an additional 1inch would increase it another 20 pounds to 40. Every inch, another 20 pounds....60,80,100 etc. Now if you added a 0.250" preload, the first inch would now require 25 pounds to compress that 1 inch. 0.500 inch of preload would require 30 pounds etc. After the first inch it would gain still only the 20 pounds.
What I'm curious about is would the additional inches be added onto the amouts of preload you had? Like this: straight would increase 20, 40, 60, 80 etc. But if you used the .500 preload example, 1st inch would be 30, now would it then increase for the additional inches in increments like 30, 50, 70, 90 etc. Hope that is clear, I was just curious. Thanks

Im not so sure about the 1st inch of travel but form the graphs ive seen preload has most efffect on the 1st inch and less as the fork compresses.
