It looks like it would train your slow twitch muscles for power, but not fast twitch for speed. The guy's swing at the beginning and end of the video looked ridiculous although maybe he bombs it. If that's the swing you develop using that thing, NO THANKS!
 
Plus it would train you to muscle the club and try to steer it through the ball instead of swinging it. It looks like a good core exercise, if you can do it both directions. But swing training? It would be a train wreck for me.

IMO, groove sharpeners dont work because all they do is cut the grooves deeper.  If the shoulder of the grooves are still worn down and rounded off, thats not going to really help.  What you really want to do is to CNC mill the face of the wedge, so that the shoulders of the grooves and sharp and square again, like when the club was new.

Since I haven't seen another model similar to yours, I have to agree. I do think the wrists unhinging is part of the equation though. That action is increasing club head speed dramatically.
 
I also agree that it and the rotation are not something you muscle through the ball. As long as you don't throw the club head away too early, it will happen. You just have to move with it to avoid hindering that action.
 
Keep at it. It's interesting and far more realistic than the linear double pendulum I've seen used over and over.

I've always taken issue with the model of a linear double pendulum because it doesn't account for the rotation part of the equation.
 
Where I think people get that rotation wrong in their actual swing sometimes is they over or under do it. They under do it with an over the top move where they've learned they have to hold off the club or they'll hit a big pull every time. But then they're slicing.
 
They can over do it by picturing 180° of rotation with their forearms in relation to their body, but don't consider that their body is rotating at the same time. Add the two together and it's too much.
 
I would guess based on what I feel, the forearm rotation is roughly 120° in relation to the shoulders? That's really just a guess not based on any measurements. Have you studied that to put a number range on it?
 
Honestly though, while your model is an improvement on the double pendulum, it's not a new revelation to golf theory to put your name on. Some have adopted the double pendulum for it's relative simplicity to model. I've never put much stock in it because it's using a two dimensional movement to model a three dimensional movement. It can't fully accomplish it. But there's plenty of teaching that includes that rotation. If your back shoulder doesn't turn through, you'll run out of arm which will pull on the club, prevent that release, and make for a slice for example.
 
But good job on the model. It's the best rendering I've seen.

Type it in every time! Just kidding!
