Changing the dogbones changes the leverage ratios, or rather changes the relative position of the linkage which is connected to the spring, so its force isn't linear. Yeah its all very complicated geometry and some calculus, but luckily is not all that critical unless you are on a race track going 10:10ths. You just have to find a set up that gives you the results you are looking for and then accepting/get used to the resulting behaviors. When you go to a longer link (to lower the arm) is put the arm/shock further on the force curve acting like increased preload (sorta). Going the other way reduces it, which in this application is a good thing, you want softer to take advantage of the available travel, but its not perfect, and any change in suspension requires adjusting/changing everything else.
