Is there or could there be a way to see the averages of the scores of players you have won against at the times you won or the average of the points won per win? A Major who has won (or lost) an average of 35 points per win (or loss) has played a much tougher field than one who has won an average of 8 points per win.
Granted, it is not likely possible for a general to find enough field marshals to play against to maintain an average of 30 points per game, but even a general whose win average is 15 points has played a tougher field than one whose win average is 5.
