Honestly I don't know how many words I release a week. I went back and divided my novel into chapters that would fit in Tapas' 15,000 character max episodes. I release two of those "episodes" per week. So probably ~3000 words a week.
I used to upload ~1500 words daily when I first started posting, but that quickly got overwhelming (for readers--I have backlog for years). I honestly don't really see more engagement when I upload more frequently. I have such a huge volume of chapters uploaded that for anyone starting the novel now, I don't think my current upload schedule is much of a factor. I'm not seeing new subs come in the same day I upload anymore after the site changes shunted community series off into their own special hell.
