Def not trying to be argumentative so sorry if it's coming off like that...
It's important to flesh out the data we are seeing imo.
So I called Libertyville, IL Tesla and talked to someone in the sales department. They confirmed that my understanding is correct that the percentage reflects the amount of resistance the system is providing in a given direction with 0% being no resistance and 100% being maximum.
The suspension changes the resistance of each shock over the course of ONE bump.
The analogy is catching a baseball. When the baseball is coming your glove is open and ready. As the ball comes you move your hand back AWAY from the glove to absorb the balls inertial weight. Once it hits the glove you then SLOW DOWN the glove speed to prevent further travel. Another analogy is jumping and landing, how you use your knees to absorb OVER DISTANCE the shock of landing.
The adaptive system in the comfort setting is in a default SOFT (low resistance, 0-4%) state. Once a bump is encountered that is higher than the road surface the low resistance allows the wheel to rise up as easily as possible which prevents car body movement. This compression of the shock is then slowed in that direction by increasing the resistance (and is probably handled with the electrical impulse as Steve theorizes, default state is no voltage).
The bottom line is that the suspension resistance changes in the comfort setting from an initial-soft to more-firm for each bump.
I'm just trying to help you guys get good data to help solve this. I won't post anymore on it as I've said my peace!
