I've noticed a lot of platforms (blogs and such) list how long they estimate for a specific essay/post/article to take for the average reader. How is this calculated?
I always read fast, so I can't just time myself -- plus, if adding a time-estimate to my own works, I'm going to know what I mean to say, and my reading-speed will be pretty fast. (But if I'm actually confusing and making a lot of assumptions, no matter how short it is, a not-me reader will take much longer.)
Is there a standard bot everyone submits to, or some other resource/calculation?
