Freemints30's post says it all.
For me, I posted my first story daily for 90ish days straight, which helped it gain popularity but I think a lot of readers weren't able to keep up with it and had to catch up to the story after it finished. So for my newest one, even though it has a 100+ chapter backlog, I am only doing 3-4 updates per week.
Tapas is about the long game, which means it will take a whole lot longer on this site to do well than on Royal Road. Fantasy is a big genre, but Tapas's novel readership is just a lot smaller than Royal Road's, so it takes a long time to get a similar number of subscribers and reads, Getting into the Fresh and Trending sections is great, but posting 2 chapters in one day doesn't help those algorithms; it's just a waste of a chapter due to the 24 hour timespan thing.
