Like most randomization code, this relies on a higher number of items to choose from to produce a more noticeable random effect. With fewer modChunks to choose from, it becomes no different than the predictability of flipping coins for heads and tails.
I also created a sub Category to minimize clutter in the Element Tree. This can also become the foundation of eventually implementing a random MODX Revolution Snippet centered on categories, where only the category name is required in the Snippet call.
Also notice, I force the direct process of the modChunk before its being sent to the page.
