How much can the gymnast lose for bearing additional hand placements?

When a gymnast bears additional hand placements during a routine, it indicates a lack of control and balance in their execution. According to the judging guidelines for Levels 4 and 5, the deduction for additional hand placements is specifically set at 0.10. This is designed to encourage gymnasts to maintain proper technique and control throughout their movements, which is essential for scoring well. Therefore, the correct deduction for such an error is indeed 0.10, as it reflects the minor impact on overall performance while still recognizing that it is an important aspect of execution quality.
