When it comes to the coach's new stopwatch being helpful, it would be very useful as the time difference between the first-place and second-place sprinters is very small, with only 0.03 seconds difference. For such precise timings, a reliable and accurate stopwatch is crucial in order to make fair and accurate assessments of the racers' performance during the track meet.
