What must lifters do to submit changes to their attempts?

Lifters must notify the announcer within three minutes to submit changes to their attempts, as this process ensures proper communication during the competition. The announcer plays a crucial role in facilitating the flow of the event, and timely notifications allow for the updated attempt to be recorded and communicated to the judges and all relevant parties. This procedure is designed to maintain an organized competition environment, minimizing confusion and ensuring that lifters' choices are accurately reflected in their performance timeline.

The requirement for notification to the announcer is also aligned with competition protocols that prioritize structure and adherence to timing regulations. This is critical for maintaining a smooth operation, as changes made too close to a lifter’s turn can lead to disruptions. The timing window of three minutes ensures that the lifters have a reasonable opportunity to make adjustments after their previous attempts, allowing for strategic decision-making without compromising the overall schedule of the event.
