I understand. That's a project that interests me.

Here's food for thought:

If you're playing with feather light sticks you will get the most action if you do put more of the work in your hands. Or just use one hand. If you have a stick without a clubhead and try to swing it as fast as you're capable of, a one handed swing will produce more speed than a two handed. And the back hand will be the winner. The pivot and the Left Hand will slow you down if you use two hands! Accumulator #3 will probably be more important for swing speed than any of the other accumulators because there's a lot of leverage in just rotating the wrist.

Do the opposite and swing a heavy stick, or a normal club with weights attached. The hands and arms will have more than enough just holding on to the club and you will have to adjust things to prevent the swing from breaking down under the weight it carries. The release holds so much moving mass that you need to brace yourself to prevent the swing from breaking down. You will be forced to use both arms and the pivot to generate some speed. And you will probably not be strong enough to snap release without getting your hands serious disconnected in the process. And you will probably be forced to apply a more sweeping motion just to keep everything together.

Replace the light and heavy sticks with a golfer that is super strong and one that is super weak and it should be clear that they shouldn't swing the club the same way for the optimum result. THe rest of us aren't either super strong or super weak, but somewhere in the middle. But we are different and we need to optimise the tradeoffs involved between speed and strength differently.
