He isn't thinking too much, I suspect I know his problem, which is just that he is still learning what he does not know. Let me tell this story.
I was playing a match and went down 0-2. And my coach was watching me and said, "why are you contacting the ball so thickly, you can't swing fast with so much of your racket exposed to the ball. If you want to maintain that contact, just swing less hard." So I toned down my swing speed and came back to win 3‐2. He then explained to me that when contacting the ball head on and the ball has energy, the wind of your paddle blows the ball and the ball is gone before you have a chance to add spin. But if you contact a bit off center but still still somewhat closed, you can trap and swing hard with more open and safer angles as long as you finish the stroke correctly. This is a guy who never spoke about pronation, he just talked about starting and finishing the strokes and would describe what he wanted to see. Lots of wisdom that I never appreciated.
That was the only time he ever explained that wind theory and I don't think I ever truly bought into it. But when I started training by myself later, I began to appreciate his main point much more, that you have to choose your contact points wisely and by raising and reducing risk in practice. Good players also have similar superstitions and stories, if you doubt this, go watch Truls reviewing his Cybershape blade with Dan, note how he talks about using the points on the blade to decide whether his starting position is what he wants.
The thing is that racket angle is controlled by many things, one of Ryu Seung Min's hidden points in that video was that your body can close the racket even if it feels open to you. But this ties back to what I was saying about pedagogy vs reality. It is why whenever someone says that someone changing the racket angle during the swing by pronating the arm has bad technique, I just shake my head and wonder whether the person has ever hit a good forehand or watched pros attack semi-high balls.. in fact on many loops, if you start the racket and swing to a true salute. your racket angle is changing throughout the stroke as your body has circular joints.
So Gozo is still swinging at the ball the way he thinks is correct. There are many ways to swing at a ball, many of them look superficially similar. When you expand your mind and learn to use different approaches, you learn the limitations of your/one approach. And sometimes you need to learn the other approaches to build tools that help you appreciate the new approach. As long as you are working, no experience is wasted.
PS: by the way. What I was doing when I had most of my racket face going into the ball was trying to close the racket and swing faster to get more spin with a closed racket angle. This was before I realized that spin is not about closed racket angles as it is about the rotational effect of the stroke.
