Using the Stopwatch (Stopwatch lap mode)
You can use the Stopwatch Lap Mode to measure elapsed time and lap times, and to
recall lap times. Up to fi ve lap times can be stored in memory. There is also memory
to record the fastest lap time. Though no more lap times are stored after fi ve times are
in memory, the fastest lap time continues to be updated as required. Starting a new
elapsed time operation clears all of the memories (including fastest lap time).

A lap time is the time elapsed over a specifi c segment of a race.
Example: Car race on an oval track
