I believe TMG comes closer to my position than any other player on this site. Let me give you a tale...
Where I live, the kids have to take an exam, an oral exam. After all their years of schooling they get a chance to show how good they are at English by using it. The exam comprises a discussion with three others. Great.
Not exactly, because to have a good grade you must have a good discussion: one person doing all the speaking is not a discussion and gets penalised.
A common problem is that one or more of the kids in a group fails (for whatever reason) to speak up. If the situation is even two don't speak, you have problems. If three remain quiet, you are dead and your exam result - irrespective of your true ability, is completely screwed.
I have always objected to this - openly, in my lectures, notes and published materials. It is a truly unfair system. It is therefore entirely consistent for me to apply the same thinking to any ratings system that is affected by external factors - or, as in the case of Diplomacy, things like meta-gaming.
TMG has often used the Chess example as his standard for a fair ratings model or ideal. It works in Chess because there is no interference from other players.
I respect his position because I too believe that the only assessment anyone should be given is an assessment based on their own qualities.
Any suggestion that he is running or hiding is, quite frankly, a disgrace. He is certainly one of the best game players I have come across and I consider it to have been one of the best parts of this site that I could meet and play with people like him. He sat for me at one time while I was travelling and gave the fullest attention to my instructions and his 'duties'. A gentleman of the board if you like and probably better than his stats suggest given the problems I have alluded to.
Perhaps if we had non-rated games, expert players like him would be encouraged to stay. How can it be a good thing for a site to lose its best players?
