Spin in TP can be a little confusing…
The Spin operator sets the Spin Time which means how much time to complete one revolution (2 PI).
If we query Spin value TP returns a Spin Speed float value which represents Radians Per Second.
A Spin Time of 1.0 equals a Spin Speed of 6.28319 (2 PI)
A Spin Time of 0.5 equals a Spin Speed of 12.5664 (half second per revolution)
Internally the spin value is calculated in radians per tick (4800 ticks per second), so be careful when creating scriptOps that deal with Spin.
