Why this isn't published anywhere else

While there are academic papers and studies analyzing linguistic complexity and its relation to genre, none of them appear to be a live dashboard or recurring report specifically tracking the evolution of linguistic complexity in public domain ebooks across genres, leaving room for a unique contribution.

Uniqueness score 0.80 — assessed against live web search results when this subject was created.
