And that all makes sense. Since this test is at the high frequency 13ft/sec, this is where the valve on the FSD is wide open and providing the least resistance. This is what would be happening over say a speed bump. This allows the spring to compress while transferring the least amount of upward force/lift to the chassis. The info that is missing is what is the force at the low frequency setting? I think I read somewhere the FSD is actually stiffer than the Sport (full soft) in the low frequency travel.
