Title: Efficiency
Post by: konrad on September 06, 2010, 09:20:20 PM
Exactly how is compound bow efficiency calculated?
Is it the ratio between pounds of force required to draw and pounds of force generated while letting the string down?

I would think the data below the force mapping curve on draw and the opposing data generated while releasing would be a good place to start.

If the above is true, why are spine calculations based on the force required to draw and not release or is this a safety measure?

Efficiency is calculated by the point at which the arrow enters the heart of the victim and if it goes all the way through or not, if it goes all the way through with little effort then the bow is too efficient, or the victim is too damn close, on the other hand if the arrow only hits the victim and doesn't penetrate very far or just bounces off then the bow is said to be Inefficient !!

Glad I could help you out !!
