Under what circumstance can record attempts be loaded in 0.5 kg intervals?

The correct answer centers on the use of chip plates during record attempts, which are specifically designed to allow for finer adjustments in weight increments. Recording attempts are significant as they may establish new records within the sport, where precision in weight is crucial for ensuring fair competition. This is why the rules allow for loading in 0.5 kg intervals exclusively during these attempts, enabling athletes to attempt weights that more closely match their personal bests and record-setting goals.

In this context, chip plates facilitate the necessary precision that standard plates cannot provide due to their weight specifications. Therefore, it is specifically during record attempts that the use of these finer increments is permitted to help support athletes in achieving and possibly breaking records. This policy underscores the importance of accuracy in competitive settings without compromising the integrity of the event.
