What is the probability of coincidence that they met together, agreed that one would write a book and the other would translate it? What is the probability that the "recipient" will actually be able to decipher it, given that he knows the algorithm?

Sorry, that sentence wasn't referring to the VMS, but to my simple encryption of the English text using vowel bigrams—and thus to the “now” time.

How easy is it to decipher, knowing the algorithm?So far, it's pretty simple: Just find a space, look at the two letters to its right and left, find that bigram in the list below the text, and then replace it with the vowel next to it.

It gets more complicated later on—there are also different lists for the consonants, but I'll get to that soon. Overall, though, it’s not that easy if you don’t know the cipherer’s writing habits and dialect. That’s why I also think it’s a bad cipher. But more on that later.

And at what point does the cipher become more complicated (the same consonant lists)? Is this observed in VMS?
