It's better not to combine Rugg and Timm's work as though they are analogous.
The two have approached the VMS text in very different ways and I don't think it's fair to throw Timm and his coauthor into the same bucket as Rugg after they have put so much effort into trying to understand the VMS text.
Rugg had an idea for how to generate meaningless text quickly, but it only superficially resembles Voynichese. It isn't really that similar, so one can hardly say it's relevant.
Timm and Schinner are trying to describe the properties of the VMS text (a much more difficult task) and they are constantly updating their ideas about it.
