Compared to the number of possible assignments of that sort,
2 million doesn't sound like a lot.

Have you tried doing this to a sample of known English
text encoded in that way? It would be interesting to know
what sort of success rate you could expect if the VMS
actually were enciphered English. Without knowing that,
you can't really draw any conclusion.
