Seol likes to badmouth pointing, but the simple fact is, I've been doing it for a long time and it
does
work. It's not the be-all and end-all. But it will definitely get you in the right ball park. Looking at things like best case and worse case scenarios is also important, and depending on one's "theme" or particular role interactions, one might adjust certain point values (that's where the "experience" comes in). But it does work.
