I think she missed a few authors in other categories. Examples:
- https://www.patreon.com/Wildbow (over $6,000/month)
- https://www.patreon.com/user?u=3814558 ($8,203 per chapter, roughly 1 chapter/month)
- https://www.patreon.com/pirateaba (no dollar amount, but 4,345 patrons and a $1/month minimum tier should translate to roughly $8000/month)
etc. None of these are conventionally established authors as far as I can tell.
