    Why? Was that a reasonable model of their system? Does that apply to
    your problem?<br>

    By reading the manual sections that describe the interaction
    algorithms and parameters that work in them, and doing tutorial
    material to see some things in action - even if they're not things
    you think you want now.<br>
