How is the starting value (SV) affected by performing elements that are not required in a routine?

In gymnastics, the starting value (SV) of a routine is determined based on the required elements and the composition of the routine. When a gymnast performs elements that are not required, it can impact the SV negatively. This is because the SV is designed to incentivize gymnasts for including necessary skills that meet certain criteria set by the governing body of the sport. When a gymnast includes extraneous elements that do not fulfill the composition requirements, it leads to a reduction in the overall starting value, reflecting the missed opportunities for a higher score that could be achieved by sticking to the required elements. This adjustment encourages gymnasts to focus on the elements that align with the judging criteria and promotes the execution of essential skills for a successful routine.
