    Butler scoring is a way of scoring a pairs events in a way which is closer to teams scoring. On a board, a "par" is calculated from all the results, and you score is the IMP score for your result compared with "par". There are different ways of calculating par, a common approach is to take the average of the results having, discarded the top and bottom scores.

    For example, in a 12-table event there results on a board are:
    -1100, -200, -100, -100, 90, 120, 150, 150, 600, 600, 630, 660.
    (Scoring by match points would give: 0, 2, 5, 5, 8, 10, 13, 13, 17, 17, 20, 22.)
    The average of the middle ten results is 194, rounded to 190.
    Giving Butler scores: -15 -9 -7 -7 -3 -2 -1 -1 9 9 10 10
