How to decipher the MS?

[Bluetoes101]

I should think if 30% of words were inconsistently misspelled this should raise entropy in comparison to a perfect example of the target language, which seems to me to be at heads with what we observe with the script?


To the original question, if you think something has promise try applying meaning to the steps and see where it goes. 
Likely it is nowhere, but "journey before destination" (way of kings ref..) sometimes what you learn along the way is most important.
