To all the naysayers, do me a favor and try the following experiment:
Stand at one end of the largest room you can find. Make sure there's a table or other flat surface nearby, and stand next to it. You'll need two identical 1" x 1" squares of notebook paper or regular copy paper. Write "drunk guy" on the first one, ball it up as tightly as you can, place it in your palm and throw it as hard as you can across the room as if it were a baseball. Put your hand, wrist, arm, shoulder... hell, even put your BALLS into it if you want.
Next, write "Max Volume" on the second square, and ball it up tightly just as before. Place it on the table and "flick" it as hard as you can using your thumb and index finger or thumb and middle finger. Now, if you can even find it, go find the piece that flew the fastest and farthest, and open it up. If you've performed all the steps correctly, that piece of paper will say "Max Volume".
The point of all this is that it's not about surface area making contact with the ball, the strength of your hand, what other connected muscles you try to exert to add force, it's about the sum total of potential energy transferred to the ball. Your hand, arm, shoulder etc. aren't nearly as efficient at this as simply applying maximum tension to a finger, then letting it go. Watch anyone throwing a baseball, football, or doing anything else with their arm. They're never gonna be going so fast that you can't see it. Now watch your own finger "flicking" something. You don't really see the arc, just your finger at the "coiled" position and then instantly at the "released" position as soon as you let it go. That's the same kind of potential energy that two thumbs at the base of a trackball transfer to the ball when you press inward and then let go. It's gonna get the ball going faster and make it spin longer than any "Superman" move will. Not only that, but as I've explained, the equal forces make it as straight a shot as you can get, and you can even vary the balance between the two if you want a bit of a "hook".
Now, I've explained how my method works. I'm not just talking out of ---my bottom---, here. Everyone seems to be bashing me because none of you have thought of it, and the drunk knuckle-draggers are smashing their knuckles against the machine, but rest assured if I or anyone else walked into a Golden Tee tournament and started using this technique, all the people who keep saying "shut your stupid face" and claiming it doesn't work would turn right around and insist I stop "cheating".
Case closed.
