    The tie breakers used were
    (1) direct confrontation – in other words, the result between two players is used if they have the same number of wins. However, if there is a loop, as there was in this tournament, then this is ignored.
    (2) SOS – the sum of opponents MacMahon score – this measures how hard your opponents were
    (2) SODOS – the sum of your defeated opponents MacMahon score – the measures the quality of the people you beat

    In a small tournament with only three rounds, however, these tie breakers are often not very effective, as can be seen above, with Sam and Chris having identical values for all these tie breakers. Furthermore, the impact of losing in the first round can be very severe, as you then tend to be drawn against lower ranked players, fatally affecting your SOS and SODOS values.
