What is the deduction for a level 4 vault involving the aid of a coach?

In gymnastics, when a competitor receives assistance from a coach during their vault, it results in a specific deduction to maintain the integrity and challenge of the sport. For a level 4 vault, the deduction for the involvement of a coach is indeed 2.00 points. This significant deduction reflects the importance of independent execution in vaults, which is meant to assess the gymnast's ability to perform the skill without external help.

Although other deductions might pertain to minor errors or procedural infractions, using a coach provides substantial support that directly interferes with the athlete's performance. Therefore, to uphold competition standards and encourage self-reliance among gymnasts, a 2.00 deduction is applied in such scenarios.
