Honestly, I tend to make about a chapter every two days, approximately. But don't make yourself a schedule, because you'll end up stressing out and pressuring yourself. That feeling might lead to feeling obliged to write, which makes you lose inspiration and love writing more. Try to keep a good schedule, but don't put pressure on yourself and try to go on your own rhythm.
Your subscribers won't spam you hate comments if you update late, it's fine! As long as you're doing what you like and that you're proud of what you're doing, you shouldn't be worrying about the others.
