Thanks for mentioning my post, your earnings for 3k views are definitely sweet. That being said, my own read ratio averages around 50%, so that could explain.

In my own estimate of how much 1k views pays, the way, one of the posts used had been boosted. Since then, I've had other posts reach beyond 1k views naturally, and it varied again, in terms of earnings.

Maybe at some point all of us will finally crack the code.
