I write whenever I can (when I am not dancing or doing research), but I never share my unfinished manuscripts with the public. As a rule, I start posting chapters once the whole story is finished (not necessarily super-polished). My current novel was complete and edited before I found Webnovel and joined the company. However, I still decided to update the novel no more than twice-three times per week.
I admire those, who can not just churn out chapters, but also edit them daily. That is a most impressive feat. I don't know how they do it. And I don't think they have time to explain. I myself don't believe that I could deliver quality content daily.
My advice would be to plan everything as far ahead as you can if you really want to hit it hard. Your chapters may not be polished, but they should make sense. And don't bother if daily updates are not something you cannot sustain.
