Here's how I consider the operation and set up of the Awesomatix dampers.
The damper and spring are a unit. The damping value is fixed by the oil viscosity within the damper. The spring value is variable, we can change it by altering the B value which I call the spring gap. Changing the B value changes the effective leaf spring length. The shorter the leaf spring the stiffer it becomes, we can validate this by holding a ruler (leaf spring) over the edge of a table and pressing down on it whilst altering it's length.
The A value then changes the leverage applied to the whole unit. More leverage is achieved with a smaller A value and the greater the leverage the softer the spring and damping will feel. I guess this is more synonymous with moving conventional shocks in and out on the lower arm than it is laying them down on the shock tower.
The way I think the set up sheet works is that it produces a wheel rate based on the leaf spring length and lever length acting on that leaf spring. It does not include the resistance felt from damping. So when setting the shocks so the wheel rate is the same but damping is different does produce a different feeling shock, due to the different resistance from different damping. Perhaps a way to validate this is to remove the spring and feel only the damping at different A values.
Hanulec - I get what you are saying, I guess all I disagree with is that I'd expect them to feel different with different damping values at the same spring rate. I have big respect for you if you can push down on a car and then translate that feel onto your own car. It's something I tried for many hours when I got my first Awesomatix, as I wanted to match it to my xray but I could never get there. Very interesting to see how different people take different approaches and ways of thinking of things, hopefully there is something for everyone =]
