Keywords: Tournament
SOR
SOR stands for Sum of Ranks. In a tournament where you play 5d 4d and 3d your SOR is 12. If kyu ranks appear it gets slightly more complicated :) Try using 7k as -6 and 1k as 0.
Motivation
This tiebreaker is trying to assess who had the toughest opponents in obtaining their score. It is a greatly simplified version of tiebreakers which use pre and post ratings in assessing who had the best performance.
