A key to understand the VMS

[Sam G]

Suggesting that some symbols represent vowels assumes that the symbols represent either letters or sounds.
Both are natural assumptions, but I have very severe doubts about them.

Like I asked above: what other possibilities are there that can account for the evidence and that can actually be demonstrated to work/exist in practice?  Obviously it is easy to discount the significance of any number of language-like properties of the VMS text by claiming that some nonexistent, undemonstrated procedure could have also produced them.

The following symbols:  q  f  p  m  y   are demonstrably not to be identified with letters.

I would like to see the demonstration of this, especially in the case of q and y.  To oversimplify, I think f p m and g can probably be thought of as variant forms of other letters that occur in certain contexts, though there's much more that could be said about this.
