What is the penalty for a cast to horizontal that demonstrates lack of control on Level 4 bars?

For a cast to horizontal that demonstrates a lack of control on Level 4 bars, the penalty is indeed a deduction of 0.20. This reflects the standards set for scoring at that level, where a cast to horizontal position is expected to be executed with precision and strength. A lack of control indicates that the gymnast did not maintain the proper body position and may have had an unstable movement entering or exiting the horizontal position, which can lead to significant penalties.

The 0.20 penalty effectively communicates the importance of control in execution, as it is crucial for ensuring safety and demonstrating skill in a competitive environment. Higher penalties are reserved for more severe execution errors, while lower deductions reflect minor flaws, thus providing a clear structure for judges to assess performance accurately. The emphasis here is on the gymnast's ability to show mastery of the skill, which is a critical component at this level.
