I took my three point "windup" charts and animated them.
Note Steph Curry's quick release. The animation starts at the beginning of each player's shooting motion. The ball is out of Steph's hands much sooner than the rest.
Derived from 2013-2016 tracking data.

Here is the overhead view (the path the ball traces if viewed from directly above the player).
While the profile view all looks like a variation of an S-curve, there's a lot more variety here from player to player.
