If _only_ it were as simple as one thing. But the truth is that distance can be achieved through a multitude of athletic motions which vary drastically player to player.

For aerodynamic objects like a disc, the optimal launch angle will be complicated because a disc's flight path is far more influenced by "secondary" (such as angle of attack and spin) compared to say a baseball, or even golf.
An "optimal" description of disc release angle that a player would likely be interested in (I say this as an ultimate player) would be given in terms of release angle, angle of attack (ie: how nose up), spin, and forward velocity.
And then once converted into human terms for all but the most elite athletes, release angle will probably instead be simplified down to windup position and release position/height.
