For what it's worth, I started buying products from Dave before computer handicapping became common. I remember my first set of Pars I bought from HSH. It was a pencil-and-paper product that included instructions for making your own speed figures. It was revolutionary at the time, and I had some remarkable success with it. However, it really wouldn't have any impact today. Same as choosing pace lines. The pace module we have does this for us. I really don't know what's under the hood, and I'm not sure I would understand it if I did. The tools are there for us to use. Our interpretation of that data is central to our handicapping skills.
