There are threads that suggest you duplicate the timeline and run it at a different time scale.
This works to a small extent but it has problems.
My way and a bit simpler is:
We get the current rotation of the elements with the hypeDocument.getElementProperty() API
We then + or - it respectively and use the hypeDocument.setElementProperty() API to rotate the elements. We set a duration to the time it takes to go from where it is to where we want.
One plus with is is you get a slight random stop.
