A member's handicap is calculated by subtracting 50 from his/her average percentage over all games played in the previous year (April to March).
The handicaps of the two players in the pair are added together and then divided by 2 to give a handicap for the pair.
This handicap is then subtracted from the score achieved in the competition to give a final percentage.
To qualify, a member must have played at least 6 times in the previous year.
