I thought of a practical use for future divination!!
So when I'm freelancing, you agree to a project and a deadline, and you estimate how long it will take and schedule the work into the calendar.
But inevitably, some of them will turn out to be way easier or more complicated than it looks (the writing quality is a lot more variable than it looked from the sample, for eg). Knowing in advance, "this is going to be one of the trickier ones, allow more time for it" would be super helpful.
Of course, better people than I assume everything will throw up surprise complications and allow extra time for every project. But since I don't do that, the divination would help.
And it would be very straightforward to test and refine my accuracy, since this is a cycle that happens many many times a year.
