Does the tower need to hold the bucket to earn the bonus?
Yes, the tower must hold the bucket to earn the bonus. Teams will not receive the Load Score Bonus (6.c.) if their Tower breaks prior to loading sand which is defined as sand being added to the bucket either by pulling the lever of the hopper or the participants attempting to pour sand into the bucket. These teams will have the mass of the Loading Block Assembly used as their Load Score (6.b.) for the purposes of determining the final event score (6.a.).
