A Rules for Foot Orienteering Events - Orienteering USA

B.18.1 It is normal to have a period of planning time after issuance of the maps before
competitors are allowed on the course, and this time is not counted in the duration
of the event. A typical time allowance is two hours for a 24-hour event. This time
should be stated in the meet announcement.
B.19 Scoring
B.19.1 The event shall end at precisely the set number of hours after the actual starting
time, both times as defined by the organizers' clock.
B.19.2 Teams finishing late will be penalized at the rate per minute or part thereof
specified in advance by the organizers.
B.19.3 Teams finishing more than thirty minutes late shall be deemed ineligible for a
placing and their result shall be recorded as overtime (OVT).
B.19.4 A team score shall be the value of the checkpoints visited and correctly verified in
accordance with these rules, less any penalties. The team with the greatest score
or in the event of a tie the team that finished earlier shall be awarded the higher
placing.
B.19.5 The most common scoring schemes use the number used as the control code of
the checkpoint to give the score value for the control. Usually it is worth either the
value of the control code rounded down to the next lower multiple of 10 (e.g.
control 67 is worth 60 points), or else exactly the value of the control number.
Points are deducted for being overtime. The most common deduction scheme is
10 points per minute late. Other schemes might be acceptable, but should be
explicitly discussed and explained at the time of a sanctioning request. Other
scoring methods could be submitted to the sanctioning committee for
consideration, but different schemes tried in the past have generally met with
competitor dissatisfaction.
B.19.6 In the event of a checkpoint being damaged or deemed misplaced or missing by
the organizers, teams shall be awarded the checkpoint score:
B.20 Awards
a) If the punch is missing or damaged but the team has a correct record on
the intention sheet.
b) If the punch is missing and there is no intention sheet, but the team can
satisfy the organizers that they visited the correct site.
c) If a checkpoint is missing or misplaced but the team can satisfy the
organizers that they visited the correct site.
d) For a correctly recorded visit to a misplaced checkpoint.
B.20.1 Awards will be given to the first three places in all categories, but a single
physical award may be used for a team which has achieved awards in multiple
categories.
