Paul,

I've gone through stages of recording the Nuerals however now I've just started backtesting/keeping records of my own ratings that i've put together. I think I prefer to know whats going into producing the ratings myself rather than flying blind on just the results. I guess both ways work however I find it rewarding the process of putting them together and following their progress.

Have always enjoyed fiddling around with Excel and equations and problem solving, I think thats why I enjoy the punting game.
