Hereās something interesting that will screw with the minds of the scientists. Please bear in mind that I am very scientific, but when you dig in deep enough, you find you have no choice but to yield to the artist.
We can gather data on the swing - everything from kinetic sequence to pressure traces etc. however, none of this (apart from launch monitor data) can tell you whether a shot was world class or horrific.
ābut what if we add more dataā?
The only way we could tell whether a shot was good or not from biomechanics data would be to delve into it in such a precise amount, looking at mm accuracy (because, remember, the diff between a good shot and an awful one can be 2 degrees of face angle, or 1/4 inch of arc depth).
However, something strange happens when we do this.
What you find is, even the best players in the world, at that very precise level, actually use a different combination of variables each time. The swing may look the same on the outside, but the things that makes it work (think, the difference between Adam Scottās best and worst shots) are never the same from one swing to the next.
Research (wiki is a good beginner source) the uncontrolled manifold hypothesis. It will blow your mind, if you can understand it.
