Oh son of a gun- it depends. Usually writing 3000 lines which is my normal episode length- I would say around a week. Ugh and with overlays getting approved why not add a couple more days to that. It’s legit soooo time consuming but the outcome and the fun during writing is worth it.
Uh well I just started to revamp my one story which originally had 17 episodes- but I have revamped 6 of them so far. My other story has 13 episodes which was a short comedy story.
Honestly- do whatever makes you feel comfortable. If you want to post in a week or maybe even a month go for it. We know how much time it takes to publish.
