For additional jumpers, how much length is added based on the standard rule?

When determining the additional length to be added for each additional jumper, the standard rule specifies that 75 yards should be added for each jumper beyond the first. This guideline helps ensure that the jumpers have adequate space between them to maintain safety during their descent and landing phases. The length added accounts for factors such as parachute deployment, descent rates, and separation necessary to avoid collision or interference in the air. Thus, the correct answer reflects this crucial safety standard for jump operations.
