New Zealand Orienteering Rankings Explanation

The formulas used for the ranking system are based on the quality of ranked runners who are running in a race. This ranking list will be the offical list of the NZOF and no doubt be used by the selectors. It will be updated and published regularly in the New Zealand Orienteering magazine. Rankings are calculated in a number of steps: 1. CALCULATE RANKING POINTS FOR EACH EVENT - Process A grades only - Find the 3 lowest ranked runners running in this event for each class where each person in a class is checked against the ranking points file. - Calculate the rankings for each competitor using statistical formulae. - If you DNF/DSQ you will get the equivalent of the estimated winning time in points. 2. CALCULATE AVERAGE RANKING POINTS FOR PERSON PER CLASS - Calculate an average for a ranking period - Set number of counting events to be equal to 4 - Minimum of 2 events 3. SET LOWEST TO ZERO - find the lowest average ranking points for each class. This may be negative. Subtract this value from all ranking points for the class. This will mean that the highest ranked person in a grade will have a ranking of 0.
