During a Level 4 bars kip mount, what is the deduction for failing to take off from both feet simultaneously?

The deduction for failing to take off from both feet simultaneously during a Level 4 bars kip mount is 0.10. This is because the execution of skills in gymnastics is not just about completing the movement but also about how precisely it is performed. The kip mount requires a gymnast to show mastery and control, which includes taking off evenly from both feet. When a gymnast does not achieve this, it indicates a lack of coordination and balance, which is critical at this level. Therefore, a deduction of 0.10 is applied to reflect the significance of this error in the overall performance. The emphasis is on maintaining the standard of technical execution necessary for successful performance at this level.
