Actually it’s wrong, kind of. Constant forces like friction and inertia are just that constant and are based on percentage of TD Max force, there is no signal strength in play.
Damping max force is percentage of max TD force but because it’s proportional to speed of rotation (acceleration) it needs to resist, makes it also dependent on signal strength.
EDIT: From SC2 manual
Damping
Damping is a torque effect which is relatively to the speed of the torque command change rate. It dampens fast torque effects that are the result of the FFB updates from the simulator. The faster torque effect changes, the more torque is generated to resist this motion.
MMOs for instance also had Effect Saturation setting, not sure how useful it would be for SC2 users but it effectively allowed to control ramp up of Dampening resistance, see chart below.
Chart also makes it easier to understand relation between speed of rotation and max damper resistance.
