Sigh. Here we go again.
The sling is not a mystical weapon imbued with ancient power that cannot be described by mortal maths. It’s a piece of string. That string acts as a transmission system that converts the high-strength but slow speed of an arm into a faster motion of a rock... as CA said, it basically acts like an extension of the arm, but he is also grossly oversimplifying it. An arm-length sling does not double the speed, because the sling lags behind the hand at some angle that brings it closer to the center of rotation. The effective length of the arm extension is less than the length of the sling. If you assume that the arm moves in a circular motion, the sling increases the speed proportional to the effective added length.... if the arm moves at the same speed with or without a sling.
Now... on to the original question: power. The sling does not create power. It transfers power from the body. If you transfer 80% “arm” power into a 120g rock with your arm, and 80% power with a sling, then the power of the rock is
EXACTLY THE SAME! Certain athletes have simply learned how to transfer power more efficiently without an extension. I know most people don’t drive stick-shift anymore, but it’s a lot like driving a car at 60mph in second gear vs third gear... either way you’re driving 60 mph. It’s just a lot easier to do in a higher gear.
So if I read you right NOOC you, surprisingly I might add, are of the opinion that the sling is a mystical weapon imbued with ancient power that cannot be described by mortal maths?
I think that’s a new and bold direction to go considering especially you are an engineer who lets face it can be a stubborn lot. I do have to praise you for your forward thinking and opemindedness.
Along those same lines I tend to burn sage and center my chakras with an Amethyst crystal before heavy slinging sessions so as to harness my chi for maximum zen during my session.
