Lists of point failed to be culled

I have randomly selected some points from a set of points, and I am trying to cull them to extract the remaining. However, when I plugged the random list into the Cull pattern battery (red arrow), the random points does not appear to be removed and the entire point set is still there. Does anyone know why I couldn't cull the random points?

Cull Pattern expects a list of boolean values (true = keep, false = remove). You're plugging in a collection of points.

Looking at your file it seems like there would be easier ways to achieve what you're after. Are you looking to remove exactly X points from a collection, or keep exactly X?

My aim is to simply divide the set of points randomly into 4 groups. For example A, B, C, D. Therefore I was trying to use the random component and the cull pattern to cull the group A generated by the random component to get 2 lists, etc. Is there a correct method of doing this?
