Sažetak
The Association of Recreational Table-Tennis Players in Zagreb (SOKAZ) attracts many table- tennis fans in Zagreb and its periphery. In spite of nominally recreational aims in these table- tennis leagues, there are many indicators to believe that SOKAZ gathers both recreational players as well as former elite table-tennis players. Among various methods of table-tennis team performance quality analysis, on the basis of the team's results in competition, the uncertainty coefficient of match outcome could to a large extent explain the uncertainty of competition. Thus, the main goal of this research was to attempt to determine possible correlation between the competitive level in SOKAZ leagues and the uncertainty coefficient in the championships for these leagues and, furthermore, on the basis of the correlation established eventually to adjust the competition system by attempting to raise the level of uncertainty in competition. This research has provided the data analysis of all the matches played in all SOKAZ leagues, during championships from autumn 2003 until autumn 2006. The research has ascertained that during all seven championship leagues the uncertainty of the matches showed a constant statistical decrease with the ordinal number of the league. On the basis of these results corrections in the competition system of SOKAZ leagues have been proposed by dichotomization of ''better'' and ''weaker'' leagues (with faster acceleration for the teams in “ weaker” leagues), as same as some proposals for future researches.
