Because we don't know if VMS spaces are word boundaries, you also have to calculate how often the "and" word (in any given language) occurs as a syllable.
For example, Latin "et" occurs as "and" and also occurs as a syllable that has nothing to do with "and". Also, in many languages the conjunction "and" is attached to words (does not appear separately).
And, as I've mentioned previously, "and" is often expressed as one character (ampersand) in the middle ages, in many languages. This possibility must also be considered. Keep in mind that the ampersand character was also sometimes used to designate "et" as a syllable (usually at the beginnings of words in Latin-based languages) even when it does not mean "and".
