What is the bonus for a C + D acro combination on the beam?

The bonus for a C + D acro combination on the balance beam is 0.20. In gymnastics scoring, elements are graded based on their level of difficulty, with a C element typically being worth 0.6 to 0.7 in difficulty and a D element worth 0.8 or above. When a gymnast successfully performs a combination of these two elements, they can receive a bonus for the higher level of difficulty.

In the case of a C + D combination, the 0.20 bonus is applied because it recognizes the skill level and complexity of linking a more difficult element (D) with one of a medium level (C). This bonus is part of the scoring system to encourage gymnasts to attempt more challenging combinations to improve their overall routine scores.

Other potential bonus values, like 0.10, 0.30, and 0.40, do not accurately reflect the combined difficulty level described in the question. Each of these values corresponds to different types of combinations or execution bonuses that relate differently to the level of elements executed or the overall scoring criteria in the Code of Points. Thus, the correct understanding of bonuses associated with specific combinations is crucial for accurate judging and scoring in gymnastics competitions.
