1.5.3 Competitors carry their own punch. They may punch, or ask an escort to punch, their card. The competitor should punch, or have punched, their control card to record their choice of marker in the terrain deemed correct. At the most technical level, with championships and courses for the most experienced competitors, there is the option that none of the markers are positioned to be correctly in the centre of the circle. This decision should be recorded in the blank box.
Any line showing more than one punch mark, or no punch mark, is deemed incorrect.
No change in punching is permitted. A correctly punched card should be displayed after the last start time. The planner may wish to display a map showing the exact location of all control markers. The competitor with the highest correct score is the winner. In the event of a tie, the competitor recording the shortest total time to make decisions at designated controls wins.
