Wrote this up in the lounge but I think a new thread is appropriate.

The question starts with "how much right hand in a swing or lefrt hand in a hit?"

Let's examine the right and left hand/arm contribution. I read a article a while back where a golfer did some one armed swinging. As I recall- the golfer had a 2 handed swin speed of about 100 mph, a left arm only swing speed of about 86 mph and a right arm only swing speed of about 90 mph. off-hand, it would show that swinging or hitting-we can argue later which it is- the second hand is a major contributor.
Using the numbers I remember - if swinging the left alone , 86 mph, contributed about 75% to a 2 handed 100mph swing -therefore the right would be the only be the only possible power source for the remaining 25% and if the right arm alone can produce 90 mph would be about 81% and the left must produce 19% of the power to reach 100 mph 2 handed.
I give U the answer now I leave the mechanics of the solution as an exercise for U.
