Popis: Scoring system of the heptathlon disciplines is lately subject of extended debates about their fairness and validity. The issue is based on a noticeably larger progressive steering and rewarding results in some disciplines and defers others. Difficulties arise from principle of progressive value of the scoring interval, trade- off between the disciplines scores and the non- additivity of the events in the aggregation process. The aim of this study is presentation of new scoring methods (incremental scoring system). Scoring results and function of the (new) incremental scoring system are compared with current scoring system using IAAF heptathlon data the WC, OG, WJC, WYC between 1997 and 2014 and 500 random generated. Current scoring system in heptathlon has a strong influence on the heptathletes preparation and training, which means that competitions are already shaded by the scoring philosophy. To avoid this feedback between training and scoring system, this study explains construction details of the new scoring system. The new approach assume mathematical function which is more flexible and make process of evaluation more objective in a way to reward maximal individual achievements redistributing the total current score on a new way. Used equation (si ‒ si- 1=αi∙ (xi ‒ xi-1), i = 1, …n) reflects the idea that the improvement in the score is proportional to the improvement in the result and the proportionality factor is greater for the higher quality (better) results. The model is still in the development phase.
