One thing to note about the above dyno data... it looks like the "curves" for the bound/rebound are linear with a slope change at 0.1m/s.
Also, it doesn't look like the chart describes how the adjuster changes the curve... is it possible that the adjustment knob only moves the switch-over point between the two slopes (like a brake bias valve)!? If that's the case, then that would explain why the adjustment doesn't seem to have any useful effect on the bouncing from the very small bumps on the freeway...
Someone get Nate or Gary in on this!
