The results of the comparison using the MLM of OEL and OIL variables analyzed among the three games are presented in Table 6. The results of the MLM showed improvements in the marginal R2 with respect to the conditional R2 in all variables, controlling for the random factor of the individual response of the subjects. The model is only significant in 15 of the 23 variables analyzed, so in 8 variables, it would not be necessary to control the individual variability of the referees. In most of the variables analyzed, the Interclass Correlation Coefficient (ICC) is moderate-low, which suggests that the individuality of the referee has a poor effect on the results obtained. As can be observed, only three differences were identified in three variables.
