This one is tough to articulate. I'll try again.

The draw force curve represents a certain amount of stored energy. One that comes to peak weight quickly but at lower weight has a more rectangular shaped curve. One that gradually comes to peak weight, but goes to a higher weight has a different shaped curve. Let's pretend that both represent the same amount of store energy. Will the kinetic energy produced, be greater from one or the other, because of the efficiency of the design of the cam that puts forth that particular draw force curve?

I'll try it another way. Let's assume the cams were put on two identical bows, only difference being the draw weight of the limbs. The heavier limbed bow will have the cam with the higher peak weight, but the more gradual buildup. Lets assume both bows store approximately the same amount of energy, will there be a diffence in kinetic engergy produced by either bow?

I realize some bows will have inferior limbs or cheap bushings or other things that take away from efficiency. That's not what I'm wondering about. I'm curious if a particular cam design is more efficient at converting the stored energy into kinetic engergy.
