I see stories doing 7+ chapters a week and it makes me pause for a bit. Personally, when I see that I associate it with lower quality, be it in plot or grammar, as well as shorter chapters that feel like they lack substance. It could be totally false, and one of those stories could be the best thing I've ever read, but its my first impression. And if I don't like it, the description, tags, or just from initial bias, it doesn't matter how many chapters it has.
So while more chapters and faster release rate might attract some people, it isn't the deciding factor for clicking on and or reading a story for others.
Such is my theory anyways. Probably got something wrong lol.
