Voynichese is a numeric cipher?

[ololololo]

A good example is f2r:
okol chy chor cthor yor an chan saiin chety chyky sal
In addition to possible nulls, there is a certain order in this string: ol - ch - or - an. 
Perhaps if you try to identify such repeating elements in the text, you can create a list of encrypted numbers and check which ones form numbers and which ones do not.
I'm thinking of doing it soon...
