I think I had a bit of a breakthrough the other day and want to check to see if I'm on the right track.
The baseball swing analogy really clicked with me and I realized that I had been trying to accelerate my upper body in a very general way. Just kind of getting my arm swinging as fast as possible. However what I started thinking more about is accelerating in order to maximize power at a specific release point. Much like a baseball swing is trying to time the peak power from the swing with the ball impact.
This lead me to work more on the timing of pressing out or pushing back from the lead leg. In order to get the release point I was aiming for I found I had to start pressing out that leg MUCH earlier than I had been. I was also able to get this feeling doing a much smaller weight transfer. Similar to how one might try to hit a well placed line drive rather than a booming home run. It helped a lot to not swing for the fences every time and instead work on the timing of loading and unloading the front leg at the right times to coincide with the ideal release point.
I had some good power throws but more so noticed an increase in accuracy with this approach. I banged a midrange off the basket from about 200 feet away one one hole.
I'm having continued nose up issues I am trying to correct, I think in the middle of my swing I lose the "coffee pour" wrist I start with.
With the new approach I'm realizing the importance of getting the disc into the front pec. It seems like the smaller the angle between forearm and bicep at the power pocket the more power you can generate (if everything is timed right). I've been revisiting the 'elbow extension' post and trying to get things in the right spot.

QUESTION ON THE OFF ARM!
One thing I felt was that my lead shoulder was not providing a good base for the rest of my arm, as if my shoulders were curled in towards my chest and not allowing the full arm length to be used. I found doing the swim move with my off arm would allow me to tighten up the shoulders and cause the lead should to come back away from the chest and provide a better base for the throw. Is that part of the purpose of the swim move? I had trouble getting the timing right but it felt like a big boost.
Hope to get some more video up soon to get better feedback but I wanted to keep my thoughts here for my own benefit and to ensure I don't start going down the wrong path!
