When might a gymnastic routine be penalized with 'CJ'?

A gymnastic routine may be penalized with 'CJ', which stands for Chief Judge deductions, primarily for improper performance elements. This encompasses a range of execution errors, such as falls, major form breaks, or inaccuracies in required skills. Each of these mistakes can significantly affect the overall performance and the athlete's score, as gymnastics relies heavily on the quality of execution and adherence to the performance criteria set for routines.

In contrast, other factors like excessive time between routines, lack of creativity in choreography, and insufficient warm-up, while they can have consequences for a meet, typically fall under different categories of deductions and are not specifically marked with a 'CJ' penalty. CJ penalties are primarily focused on performance execution issues that directly impact the assessment of the gymnast's routine.
