This is very nice analysis. What is the time-frame when a post stops getting payment? Is it after a week?
I think one more thing that can get a bump is someone curates your post in services like streemian.com or steem.chat. But of late, I only notice self promotion there
To a person like me, who is pretty much stuck in a box and don't really understand how to improve the viewership of their posts stats like these really help!
