This seems to be approaching full authority feedback. New cylinder installed, it doubled the feedback force. The pedal is quite aggressive during higher engine loading. No conscious effort is required to use it. Accelerating from a dead stop now requires feathering the clutch more since it throttles back automatically.
The next step would be a constant rate spring that depresses the pedal instead of your foot. Apply pressure to the spring and you set the load for the engine and it remains constant regardless of rpm. Some people on here are using hand levers for throttling, adapting a spring to that design would make this a constant load cruise control if there would be anything to gain from it.
