The level of objectivity was evaluated by means of these indicators: number of foul calls, number of referees' mistakes, index of mistakes, and number of offball fouls. The statistical significance of the difference was evaluated in Chi-square test (χ 2 , α .05). Qualitative analysis was based on the minimum required criteria according to expert opinions of top league CBF referees (n = 26). The significant difference in the number of foul calls was not confirmed. The results showed significant difference in decrease of number of referees' mistakes and index of mistakes and in increase of number of off-ball fouls. The findings support the idea of 3PO system to be efficient.
