It's all about the laod time
you are definitely in the right area for shaving time.
I don't quite understand why the race grip uses two clocks to control the recock solenoid valve on time. they have "open time" and "load time" in series with each other. they essential do the same thing.
the cycle rate of a cocker could be very high with higher operating psi, higher cocking psi, stiffer springs and a larger valve.with light springs the valve would eventually begin to "float".I beleive you could reach 33 cycles per sec before the valve began to float in a cocker. but it damn well wouldn't shoot any paint with current loaders.
I believe that the only electro cocker capable of really high ROF is the sandridge.it is able to use stiffer hammer and valve springs because of the use of a ram instead of a solenoid.
heavy hammers are essentially detrimental to cycle speed, but they are helpful for direct solenoid actuation of the sear.
