The "Fastpitch Softball: The Windmill Pitcher" by Barry Sammons does have stationary snap drills in the Appendix... which is unfortunate. But.. it actually addresses arm whip in the text... that is... much better than most sources that followed. It even has pretty illustrations showing internal rotation... which is rare, in a book... and in life, in general.
Here is one of his illustrations for arm whip:
Here is Appendix A (was actually misprinted as Appendix D...) Look familiar... ?
And here are some more direct quotes from Sammons regarding Arm whip... or what we call i/r...
Although I'm not a huge proponent of "cocking" the wrist... this is pretty spot on...

To learn feel of the rotating action of the pitching arm during the arm whip, perform the internal shoulder rotation exercise described in Appendix A. - Fastpitch Softball: The Windmill Pitcher, Barry Sammons, 1997

And here are some more direct quotes from Sammons regarding Arm whip... or what we call i/r...
... just prior to the arm whip the angular orientation of the upper arm leads the angular positions of the lower arm and hand. That hand trails because the wrist is "cocked" and the lower arm trails because the elbow is slightly bent and the arm is pronated, or twisted to the open orientation.
... the rotation of the upper arm segment is decelerated by the shoulder muscles. As when the handle of a whip is suddenly stopped, the angular velocity of the lower arm increases and it catches up with the angle of the upper arm...
... the lower arm straightens and rotates closed (for most pitches) during this phase of the arm whip...
A key factor in this mechanism which is often overlooked by those who direct all their attention to the wrist snap is flexibility at the elbow. - Fastpitch Softball: The Windmill Pitcher, Barry Sammons, 1997
