I don't know what you mean when you state that there is a pulley within the wristcock itself.

I also don't know what you mean when you imply that the wristcock acts differently in the different release patterns.

My concept of HK's pulley (in his endless belt analogy) relates to the curvilinear path of movement of the hands over time, and a pulley exists when the hand arc over a short period-of-time becomes particularly curved rather than straight. In a snap release, the hand arc path is very J-shaped with a very small pulley, while in a sweep release it is very C-shaped with a large pulley. The random release pattern has an intermediate pulley size.
