a stiffer rebound valve to operate) and experiment with inertia valve and with the "cut-in point" of the inertia weight until the car snubs down well on a donkey-back.

Attached sketch may make this clearer.

I do not consider that inertia shocks can be said to improve the ride (and I know you will agree that few shock absorbers do). They do enable a light main setting to be used with slight orifice, while avoiding the danger of this sort of setting namely the unexpected "throw" over a long road-wave met in the dark at high speed.

4. Attached is output chart of our 5" Delco generator which I think answers your question.
