Current U.S. Trail Orienteering Rankings

The event algorithm is as follows: T O logo

Competitor’s ranking points
RP = A - B points, where
A = Competitor’s score/Winner’s score x 100 and
B = (Competitor’s time / Maximum time penalty) x (100 /  Winner’s score)       
Example:
A competitor has 17 controls correct with two  timed controls = 55sec.   The winner had 20 controls correct.
A = 17 / 20 x 100 = 85.0; B = 55/270 x 100/20 = 1.02; RP = 85 - 1.02 = 83.98 pts

For the Ranking list
The sum of the top 3 Ranking Points for the last 7 OUSA ranking events and WTOC events for the same time, are divided by 3 to determine overall ranking. Apparent ties are resolved to the 4th decimal place. Trail O Event Directors and Course Setters receive a credit.
