For Grassblades, I release one page every Monday, and one page every Friday, so twice a week. : ) I'm able to keep that schedule up, even with a full colour comic, because I have a very big buffer of pages (50+), and because I take a week's break between each chapter. And also by being obsessively organised about it.
For Wishlight, I'm releasing one update a day for 24 days, as it's a calendar comic, but I finished the pages in mid-November.
Also, for the past year, while working on Grassblades and Wishlight, I've also managed one 30-page oneshot, one 12-page oneshot and one 7-page oneshot comic, as well as a 32-part illustrated story for Inktober, and right now I'm attempting a daily challenge of doing one illustration per day inspired by my tea-calendar - Tea Witches.
.... I'm a workaholic. Don't see my example as one to follow. It's only recently that I've been able to get my sleeping-schedule back to a healthy pattern.
