My comics is a long scrolled format which usually has 7.5 panels average. But I only upload twice a month, meaning 15 panels a month on average.
As of recent, I have action scenes which is a bit hard to do but at least I use 3D for the backgrounds so I don't have to draw them all in different angles.
When talking about fastest I've done on record: I did 8 updates/pages which was uploaded within 10 days. (Note: multiply by 7.5 panels per 8 updates and I get 60 panels for those 10 days).
That makes 6 finished panels per day. Fastest I've done as of recently.
Which was extreme for me but it's doable when I'm very focused and have nothing else to do but I don't think I will be binge drawing that frequently. But I want to just say do not push yourself, draw at your own pace. My personal experience, that I just shared, is just for reference.
