Abstract

Starting with some considerations on the scoring system in an orienteering race used in Italy, the author examines the main aspects of the Elo chess ranking system in order to show how it can be adapted to orienteering, creating the OriELO system. The OriELO system is based on the ranking position and the quantification of the arrival time compared to the time estimated on the basis of the relative strength of the opponents. The basis of the Elo ranking system and the proposed OriELO system is the likelihood of a win or defeat in a direct confrontation, given by a logistic distribution. Here the theoretical explanation with formulas is followed by a simulation.
