The supination comment was said flippantly because I wanted to use a fancy word.
In practice, If you want to feel what the foot should do, build a hitting board with a wedge.
Of course this isn't about the foot. But the underlying prmise is.
My whole line of questioning was going towards what you said regarding shoulder tilt and the incoorect notion (IMHO) of turning the barrel (HPP). The Either clip on and inside pitch is a good example. Turn the barrel (HPP),miss the ball, on the inside pitch. That's is irrefutable, IMHO. If someone doesn't agree with me, okay, IDGAF. If you and FFS want to talk in terms of body go ahead knock your socks off. But I'm just not interested because it doesn't translate to an child. I could've talked about angular velocity and torsional compression to my DD, but would that translate? Only if she too was an engineer. My advice is to keep the double speak to a minimum and becareful drawing 2 dimensional lines and dots on a 2 dimensional video whcih is footage of a 3 dimensional occurance.
Happy Thanksgiving
Over and out.
Can you explain this just a little be more. What am I looking for or feeling for off the wedge? More of a rear leg/foot drive? It maybe a stupid question but, just trying to make sure I have the correct purpose. While I'm waiting for the turkey to cook.
