The system is based on fundamental game theory of the zero-sum games. It offers a ratio scale, starting with zero for the strongest play up to 80 for beginners.
It was started in 1922 by Bruno Ruger in Dresden. And it was in common use before and after World-War II till to the mid 1970s. That was valid all over Europe at that time i.e. Germany, Austria, Yugoslavia, Netherlands, mainly. In addition to describe its historical origin, we want to show the important aspects that even now are of interest for us. Discussion about statistics shows the better quality of rating by ratio scaling against conventional ranking. The evaluation of tournament results proves the assumptions. Considerations are given about quantitative measuring of psychological behaviour.
