I think you are better off by not using a "random reduce" from the start, and by creating a random boolean pattern to dispatch your list of points. Check out the two methods I propose in the attached pic!

Why "better off"? Alternatives are great, "better" needs to mean something...

By the way, you don't need the 'CSet' components in my example. And I prefer to multiple the length of the point list by a fraction between zero and one instead of dividing by an integer; much easier than a cull pattern edited manually.
