The only thing that matters is how the disc leaves your hand, and how reproducible and flexible (to deal with a variety of scenarios) is the motion you use to make it occur with minimal error. After watching lots of pros, I pop all my fingers and thumb open quickly upon release. That's what gives the impression of "shaking hands," and the purpose is to calibrate the timing of the release as well as to get your fumbling stupid fingers out of the way so they don't screw anything up. I also need to give the disc the speed and air it needs to hit the chains at the sweet level, and that requires throwing with more force, more purposely, almost punching at the basket. For example, watch Josh Anthon putt some time (or on youtube), the guy's arm and wrist come out and strike like a cobra. It's an anhyzer-flex/spin-putting style. The disc comes out of the snake's mouth as it strikes, and darts right into center chains. Dialed-in!
