New to this, and trying to create something that will allow me to remove the top 40% of a list of volumes. Having some issues, thing it might be something simple. Was directed previously towards cull index, not sure if this was the correct way to do it but it did seem to get me quite close. When culling it seems to still pick a random sample to remove.
I have attached the file in the hope that it helps someone out more than my words.
