Table 9: Support difference of the most favorable conditions for tactic application when evaluated across other tactics. seconds (_play duration_\(<6\) s) and in which the goalkeeper did not attack the ball (_Goalkeeper leaving line_\(=\) False), led to more successful than failed plays. These conditions were present in 59% (887/1515) of successful plays using this tactic, compared to only 22% (777/3459) of failed plays, resulting in a support difference of 0.37, the fourth largest across our tactics. Notice that this tactic is used in 4974 plays, representing roughly 76% (4974/6541) of the total number of corner kick plays that conclude within the _Penalty Middle_ region. With this pattern, we show that in some cases, some conditions may be more interesting than others in determining the success of a tactic. For example, the condition in which the goalkeeper does not leave the line is present in over 98% of plays using this tactic (see Appendix A). Therefore, this attribute may be less critical in anticipating the success of the tactic. Furthermore, successful plays tend to be shorter than six seconds. However, the duration of a play is often beyond the control of the offensive team and is likely a consequence of the outcome. Therefore, from a practical standpoint, the player's height attribute may be more relevant than the other conditions. A correct interpretation of the results can be crucial for effectively supporting decision making in the field. In the case of the **short variation** tactic (CPID = 5), plays that were executed by offensive team players whose average height was 177 cm or more (_play avg. off. height_\(\geq\) 177 cm) in roughly less than 19 s from the time the corner kick was awarded (_preparation time_\(<\) 19 s) and in which there was a fight for the ball (_num. duels_\(\geq\) 1), led to more successful than failed plays. These conditions were present in 50% (13/26) of the successful plays using this tactic but only in 13% (12/95) of the failed ones, resulting in a support difference of 0.37, the fourth largest difference across our tactics (tied with the support difference for the _direct_ corner kick). Notice that this tactic is used in 121 plays, representing around 7.8% (121/1567) of the indirect corner kick plays that conclude within the _Penalty Middle_ region. However, since the _direct_ corner kick tactic has a much greater usage, this tactic represents roughly 1.8% (121/6541) of the total corner kick plays that conclude within this region. Interestingly, this is the only tactic in which the preparation time appears among the most favorable conditions. For the **short** tactic (CPID = 6), plays that were executed by offensive team players whose average height was 174 cm or more (_play avg. off. height_\(\geq\) 174 cm) in less than eight seconds (_play duration_\(<\) 8 s) and in which there was a fight for the ball (_num. duels_\(>\) 1), led to more successful than failed plays. These conditions were present in 55% (40/73) of the successful plays using this tactic but only in 21% (45/217) of the failed ones, resulting in a support difference of 0.34, the fifth largest difference across our patterns. Notice that this tactic is used in 290 plays, representing around 18.5% (290/1,567) of the indirect corner kick plays that conclude within the _Penalty Middle_ region. However, since the _direct_ corner kick tactic has a much greater usage, this tactic represents approximately 4.4% (290/6541) of the total corner kick plays that conclude within this region.
