I am just narrowing the scope of "rating" to two player games, and calling the rating by a different name so as not to confuse the two.
Since Fencer has decided on a system, there is no need to continue this.
To answer his question, I thought we were still in search of a system. I was asked by CzuchCheckers to post it in his "Ponds Plus" DB, and the suggestion was to also post it in here for discussion.
As it is no longer needed, I will no longer post on the topic.
