G <strong>Rules</strong> <strong>for</strong> O<strong>USA</strong> Rankings<br />
G.1 <strong>Foot</strong>-O Rankings<br />
G.1.1 The chairperson of the ranking committee will publish the annual rankings of all<br />
orienteers who meet all of the following conditions:<br />
a) Are <strong>Orienteering</strong> <strong>USA</strong> members at anytime between January 1 and<br />
November 15 of the ranking year.<br />
b) Earn daily ranking points in at least four races on the same color course in<br />
any class except M/F-White or Group (Gr) classes.<br />
G.1.2 Daily Ranking points from competition are earned by:<br />
a) Competing in one race of an individual <strong>Orienteering</strong> <strong>USA</strong> sanctioned A-<br />
meet with individual staggered starts (including restricted events), on a<br />
course proper <strong>for</strong> your age that is not invalidated by the Jury or Meet<br />
Officials, and completing the course or receiving a disqualifying<br />
designation as in section G.1.3 below.<br />
b) Completing a course above the course that is proper <strong>for</strong> your age at a meet<br />
satisfying the criteria in G.1.2a above.<br />
c) Completing a course at the North American <strong>Orienteering</strong> Championships,<br />
even when held outside of the U.S., in a class equal to or higher than the<br />
<strong>Orienteering</strong> <strong>USA</strong> class in which the person will be ranked.<br />
G.1.3 Persons who are disqualified (DQ), do not finish the course (DNF), or who are<br />
overtime (OVT) – <strong>for</strong> any reason, including injury – are assigned a Daily Ranking<br />
Score of 0.<br />
G.1.4 Daily Ranking points earned by competition are calculated as follows: The<br />
Course Difficulty is calculated from the average of the Personal Course Difficulty<br />
of each competitor, which is the competitor’s ranking points <strong>for</strong> that race<br />
multiplied by their time in minutes.<br />
a) This calculation is circular, so the Iteration Method is used to determine<br />
each competitor’s ranking points. All competitors start with 50 points,<br />
and the calculations are repeatedly per<strong>for</strong>med until the results converge.<br />
b) The average Personal Course Difficulty is a harmonic mean, which is the<br />
reciprocal of the arithmetic mean of the reciprocals. This causes the<br />
results in (a) to converge and results in non-drifting (i.e., significant)<br />
results.<br />
c) Daily Ranking scores of zero are excluded from this iterative calculation<br />
process.
