Not enough valving and killing the tires suggests to me that there was a separation speed issue. Moving the shock forward for the purpose of showing lower shock speed data, while at the same time reducing that shock's ability to control actual separation speed, just having a hard time wrapping my head around how that makes the car quicker.
Here's an example- if you attached a shifter stick to the bench, and attached a shock to the middle of that shifter stick, the closer to the bottom pivot that the shock is attached, the easier it is to move the shifter handle. As the motion ratio of the shock decreases, the shifter handle gets easier to move. Speed data for that shock would show slower due to less distance traveled, even though the handle itself travels the same distance in the same amount of time.
