Having experimented with it, there is no point in posting more than one chapter a day. Having tested it at Mid, 6a, noon, 6p, I have determined that 12:00 am GMT is the best time to release it. The algorithm doesn't check more than one upload a day, and it seems to check as itis uploaded. So uploading at midnight am means that you are far more likely to wind up on the trending list.
Why?
Because if you upload at midnight, you are likely to get on the list before anyone else. Once you get on the list, you are more likely to get views, and more likely to STAY on the list.
It is a minor boost, but it exists.
If you can upload 2k a day, every day, I believe that would be ideal. I seem to have noticed that chapters with less than 2k didn't perform as well, but the sample size is low. But 1 chapter a day at midnight GMT is the core for performance.
