der Schuld: Wir sind nicht zu Hause.“ (Ingeborg Bachmann)

Usually we calculate rating as measure of strength. But in the same way we could calculate „anti-rating“ as measure of weakness. For this we have to replace „win“ with „loss“ and „loss“ with „win“. As a result of this operation we will obtain another rank-list. Ranking by anti-rating will not exactly be congruent with the Ranking by rating.
