I think part of the problem is your grip/too over the top. The nose is up coming into your center. You hold your arm weird at address and throughout the backswing where your shoulder is internally rotated the entire time.
Yeah I feel and see that, especially the arm part. My hand is too over the flight plate/angled I think you're meaning by over the top? Or I am moving my body over the top because of my grip being nose up? Either way I feel the grip weirdness and the arm turned internally.
Now that I have identified what was good about these throws I can feel how to keep more neutral for next time and trust it. It almost feels like I'll be more underhanding it instead of turning my wrist or arm back internally and then snapping them at the end. I think this internal arm rotation at address is why I was feeling all that supination on the way forward during the actual throw.
And I don't think I would actually be "underhanding" the shot, just compared to my typical disc/forearm above elbow that's likely why it feels that way. Kind of like is a spush putt an underhand or just a good transfer and pop/extension. Then likely add more momentum so the arm is higher...won't look that way anymore. I think this is the pendulum, just me feeling it relative to my own perspectives.
Just saw your last post and yeah, I've said somewhere before that my putting got better by making it more like my drive.
Yeah I remember you making some comparisons and crossover between them, but until I felt it this much I didn't realize how forward my body would face and in front the extension would be. The thumb push/finger spring feel makes sense in my putt, so it also makes sense that that'd be closer to where the throw would end up too.
The front shoulder leaning forward feel makes me think of Eric Oakley or Eviina Salonen, but in actuality I don't think it's that extreme at all. It just feels very different compared to what I've done forever.
Does it make sense to feel like the hit point is in a similar place to in a putt, but because you are snapping through instead of just extending out, the release trajectory is like 20+ degrees closed? Like I feel a similar location and balance, but if I were to leverage through this point, the disc would go way off to the side compared to a putt.
Or am I going down a weird and not right rabbit hole?
