Why the Voynich Manuscript Might Not Be a Real Language

[oshfdk]

I (as someone who doesn't speak statistese) am confused. If perplexity is basically another way to measure entropy, then why is CUVA higher than Romeo and Juliet? Even with EVA's entropy-reducing properties minimalized, we should still end up well below English texts. Or French. Or the vast majority of Latin texts...

Why so? As far I as know, Voynichese entropy is relatively low only for short ngram values, like bigrams and trigrams and gets much closer to normal with the increasing length. This is exactly what happens in the original graph at the top of this thread.
