The beginner takes the information here and tries what make the most sense, to him. And sees how it works, for him.
Because if there really were just one answer to it, it would have been overwhelming in the responses. Like most things in pool, there isn't just one way to skin that elusive feline...(and I'll grant you that even if there was one real answer I'm sure we would get multiple variations on that, as well

)
There is value in this for the beginner, it teaches you to figure out what works for you specifically, and gives examples of how it has worked for others. Far better than just figuring it out on your own without the examples.
