Suspension Upgrades & Damping
The spring carries, damping decides how fast. Two curves show what the clicks on your shock really change.

Slow and fast are two circuits.
Low-speed compression handles braking, berms and pumping, high-speed compression handles roots, edges and landings. Both sit on the same curve.
Model of a digressive rear shock with the knee at 0.15 m/s shaft speed. Forces at the shock, downhill range.
Rebound
Rebound once, not three times.
Rebound slows the return. Too open and the rear end keeps bouncing, too closed and it cannot recover between two hits.
One degree of freedom: 50 kg on the rear wheel, 10 N/mm wheel rate, compressed by 100 mm and released. A damping ratio of 1 means: back without overshoot.
