I looked at this very problem before:
1) the character entropy (h2) in the VMs is low
2) the words are on average not longer than in Latin
3) the vocabulary is as diverse as Latin.

This is an apparent contracdiction, but it turned
out that the VMs language is simply more economic.
Look at http://www.voynich.nu/extra/wordent.html
to see the details.

In fact, if a long text in a given language
has 8000 different words, the words can be
written using numbers of only 4 characters.
The alphabet size would be ten.
That gives an h0 of 3.3. The distribution would be
rather flat, so h1 and h2 would only be a little
bit lower.

Here, everything has been reduced: the average
word length and all the entropies.

I am sure that, by 'playing' with the character
set (the digits) on a position-dependent basis,
a language with VMs-like statistics could be
