This book might come from "untypical" conditions which might help to create these text statistics, possibly:
- Maybe a brand new writing system (with no "official" grammar, so the grammar might be "loose")
- Maybe multiple dialects in same text, none of these "wrong"
- Possibly multiple writers
- A poetical mindset which likes kind of similar repetitions
- Some linguistic "atoms" might use many Latin characters
- More typos than our average manuscripts
- Some characters or linguistic "atoms" might have multiple incarnations
- More synonyms than usual
