I am not sure if I deserve your fine compliments, Yoda, but therefore I appreciate it more.

Annyway, here's a discus throwing video:

The discus throwers work on an inclined plane as we do. Not sure how similar it is to ours though. Probably flatter and perhaps with a strong inside-out orientation compared to the target line. Fascinating to see how they drive their hips forward to optimize their alignment the last instance before they drive it home. There also seems to be a lot of float loading of the primary (and only) lever going on.
