Most importantly, I would imagine, doing it by hand gives you an understanding of what is actually going on; i.e. it gives you a view to the underpinnings of how the technical aspects of astrology work and, in theory, a glimpse into the workings of the universe.

Other than that, there is the mental discipline aspect and, most importantly, you can make your students do it because you had to do it too.
