What tool is allowed for timing tasks in Section Three of the Metric Mastery competition?

In Section Three of the Metric Mastery competition, the tool allowed for timing tasks is a stopwatch. A stopwatch is specially designed for measuring elapsed time with precision, allowing participants to start, stop, and record time intervals easily. This functionality is crucial in competitions where accurate timing can influence the outcome of tasks. Other timekeeping devices, such as timers or clocks, may not offer the same level of control or accuracy needed for precise measurement during timed tasks. While a calculator, timer, and clock can serve various purposes, they do not provide the same immediate feedback and timing capabilities that a stopwatch does, which makes it the preferred choice for the competition.
