I have a scene with a particle system, which emits a few planes, to which is assign a cloth simulation. A wind point force emitter drives the particles in a swirl. Cool.
The overall action is getting to be what I want with the settings shown or in the file attached.
What I would like, however, is for the speed of motion of the particles to move at something less than the speed they do now... say 15% of present. The amount of vertical offset from the force would be the same, the same swirliness.... just slower... Like if I remapped time for the scene. Since there are other things going on in the scene, I cannot really remap, however.... so I just need to control fairly precisely the speed with which the particles move.
All input welcome.
UPDATE: The solution I accepted below seems to nearly work, or I am understanding it poorly. Here's the jerky motion I am getting... usually, anyway.
