Did it take the predicted time?

If you came across this article in your Medium feed it will have provided you with an estimated read time. What is the value proposition of this estimate? It allows you to make an important decision about a really valuable thing, your time. The actual value is somewhat irrelevant as some of us (me) read much slower than others. However, it does allow all of us to gain an understand of the commitment and therefore make a decision. So thanks for spending however long it took you to read until this point.
