An Artificial Construction

But what if these are numbers?
These would get very uniform.

Yes, I think lists of numbers may work like Voynichese in this test.

Edit: However, I'm not sure about a simple nomenclator style cipher. It's relatively easy to test, just make a similar chart but with words as basic elements. In a nomenclator the selection of words that follow should depend on the words that precede them. I did run similar tests a few years ago, and I think Voynichese behaved rather uniformly at different scales. But worth retesting of course.
