"To fix a system, you first have to understand it, including it's history, and then try to create a mathematical model of the system's dynamics to challenge your assumptions. As you build the state diagram of the system, you will learn the limits of your knowledge and understanding. As you parameterize it in attempts to achieve meaningful convergence, this message will be hammered home, leading, hopefully, to greater wisdom." FitOldDog, just now!
