Pacing items are the elements that set the tempo for how fast tasks are performed in an ERC drill or operation. In the ERC labeling system, each type of item is assigned a single letter, and pacing is designated by the symbol P. This direct association makes P the best choice because it specifically communicates the function of controlling rhythm and timing. Pacing items help maintain a steady flow, synchronize actions across teams, and keep the exercise progressing on schedule. The other symbols represent different categories of items and do not indicate pacing.
