RE: Voynichese is a numeric cipher?

I will share my speculations about what the cipher of the Roman numerals in the manuscript looked like. This is not a complete model, but rather a set of assumptions.
1). I believe that the cipher can be divided into three types: the original form and the Currier's languages, which may be the result of a change or "adjustment" of the cipher to the author's needs or scribes. I consider Language A to be the closest to the "original form," because it was the first language used in the manuscript.
Original form is a simplified nomenclature cipher, where Latin letters are encrypted with Roman numerals, which are in turn encrypted with an unknown alphabet. At the very least, this cipher had two tables, one with letters and the other with abbreviations. Unlike other nomenclatures, where unique words or frequent morphemes were encrypted with a distinct combination of numbers, the manuscript cipher used a single alphabet for both tables and did not have any unique words. I don't rule out the possibility that some letters could be encrypted using two unknown symbols, as this was a common and everyday practice at the time (for example, a symbol encrypted as ee could be encrypted as ch). There's another option - there were several tables for the letters, and in one, for example, they were numbered in ascending order (A = 1... Z = 26), while in another, they were numbered in descending order (A = 26... Z = 1).
However, two tables remain the minimum requirement.
The secondary encryption process (i.e., manipulation of the already encrypted text) involved creating nulls and splitting the word. Nulls should be symbols of the same alphabet, but placed in a way that allows them to be recognized and discarded. A rough example: YMOR YNIN YG (the word morning is divided into three parts, with an added null "y"). In terms of numbers, they could be aligned, and the principle was that the word C-X-VV-V-CI became CCXVVVI. Will you say that it will be impossible to decipher it in this form? I can tell you that this can be done by focusing on the word itself. In the unencrypted form, there was a combination of CI, which is considered a single letter, and when you tried to decrypt CCXVVVI, you realize that the unit doesn't fit, you'll immediately understand that there's a letter of the form x-I in the word. This will lead you to CI. Next, you'll realize that VVV doesn't work, and you'll immediately understand that there are either V and VV or three Vs in a row (you'll soon discover that this is also incorrect). You will also understand that C is the first letter in the word, and that the combination XV is not suitable... After a few iterations, you'll eventually guess the word, and all you have to do is check the table to confirm that you've correctly guessed the C-X-VV-V-CI. While this is possible, it is also expensive, so it is possible that the author provided hints for the syllables. For example, he divided the word into CX VV CVI, preserving the structure of the syllables to make them easier to recognize.
Currier A is a classic version of this cipher. In fact, it is not certain that it was the same as the original form (for example, the scribe may have encrypted the prefix not with a separate symbol from the second table, but with letters from the first table). The supposed feature of Currier A (I would call it the scribe's approach) is the infrequent alternation of tables. This means that when writing, the author tried to avoid confusion during decoding by using specific symbols for a single value rather than two. This means that the "value" of the letter will be stable, and in most cases it will produce the same result. But it could also be more complicated, using aspects that I didn't consider.
The difficulty of Currier A is compensated by the fact that, for example, you don't have to read the entire botanical section. All you need to do is open a specific page, decipher it, close the book, and forget about it. To see if the page has the plant you need, you could decipher the first word (which could be the entire name of the plant, or a part of it) and get your bearings quickly. Briefly, the complexity of the cipher is compensated by its practicality. The practicality could also be expressed in the fact that Currier A encrypted small amounts of text, so it wouldn't take too long to work on the encryption and decryption.
Currier B, it will be derived more from Currier A than from the Original form, being a simplified and adapted form of the former. The peculiarity of Currier B is that it contains large amounts of text. If you try to encrypt a large amount of text at once using the methods described above, you will probably not want to continue working halfway through.
Therefore, it is likely that the scribe deliberately simplified the encryption method, which resulted in a more monotonous text than Currier A.
How could these simplifications be expressed? I can't say for sure, but I can assume that
a). The word could have been encrypted in its entirety or lazily (i.e., using a pure pattern)
b). The author may have made changes to the tables, one of which I believe was the addition of the Quincunx symbol (EVA x). Maybe the scribe didn't want to write 150 in Roman numerals for a long time, so he remembered that the quincunx is equal to 150 degrees and wrote it down. It is also possible that he assigned higher values to some characters than necessary (maybe this characters is ch/sh?).
In addition, the reason for the monotony of the text may have been that the author often alternated between tables, writing qo as a prefix in some places and as a letter in others.
In the case of Currier B, we need to decode it completely in order to obtain information.
So, here's my opinion on all of this: If we want to study the structure of the cipher, we need to focus on Currier A. If we want to study the flexibility of the cipher, we need to focus on Currier B.
2). What will the output text look like? In any case, we will have difficulties, because we will have to solve the anagrams of words that inevitably arise when arranging numbers. In the case of Currier B, this will be really problematic.
3). Which symbols are most commonly used as abbreviations? It may be f and p (they do not form stable combinations, unlike their counterparts k and t, and are often used at the beginning of a paragraph/page), and qo (in this form. If it is a prefix, the author could have given it a large value in advance to make it always stand at the beginning of the word).
4). The reasons for repetitions? There can be several of them: splitting a word with the addition of garbage elements, using the same word in different meanings (for example, the pair qokedy qokedy can differ in the meaning of the q symbol) or, as already mentioned, clues for decryption.
5). As for the zodiac section and astronomy in general, it may turn out that nothing is encrypted there, and the numbers themselves are written directly. We'll have to work on that, too.
And again, regarding the complexity: yes, since it is a nomenclature, the cipher will be complex, which is why we should expect it to be simplified during the writing process becoming readable.
