What is the penalty for failure to mark floor boundaries when mats are present?

The penalty for failure to mark floor boundaries when mats are present is indeed 0.10. This penalty is applied to ensure that gymnasts and judges can clearly see the designated area for routines during performances. Properly marked floor boundaries help maintain safety and ensure that gymnasts do not accidentally step on or over mats that might be placed outside of their intended competition area. The .10 deduction reflects the importance of maintaining clear boundaries, as it helps facilitate a fair assessment of the routines performed. Accurate boundary marking contributes to the overall integrity of the competition, allowing judges to properly evaluate the performance without ambiguity regarding the gymnast's area of activity.
