When an orienteer does not complete a course, one of the following abbreviations will appear in the finish-time column of the results:
DNF - Did Not Finish
The orienteer did not complete the course. They may have gotten lost, tired, or injured, or they may not have found one or more of the controls. If the orienteer doesn't mention the missing control(s) when they report to the finish, the results crew will usually notice the missing punches on the control card when they check the punch codes.
MP - Mispunch
The orienteer punched an incorrect control. This happens when someone punches a control without checking the control code.
DQ - Disqualified
It means that the competitor violated an orienteering rule, such as: taking controls out of order, running through an out-of-bounds area, getting help from others, or using an illegal navigational aid.
OT - Overtime
The orienteer took more than allowed hours to complete the course. Three hours is the maximum time allowed to run a course under orienteering rules.
DNS - Did Not Start
Indicates that a registered orienteer did not show up to run their course. Mainly used to indicate a person is not still on the course and a search is not started.
