Circuit Events
Circuit Events need to record the lap time and total time (cumulative lap time).
In addition you may like to know:
- The fastest and slowest lap time
- The average lap time
- The lap speed
- The stroke rate
- The time of day at the start of an event
- The time of day at the end of an event
- The gap between two competitors on the circuit
You may want the additional functions:
- The ability to store split times in memory for recording after the event has finished
- The ability to review memory at any time during an event and still capture a lap split
- The last lap time displayed in addition to the current lap running time.

Example: Motor Racing 
Example: Athletics - The last lap time displayed in addition to the cumulative running time.

Example: Swimming - The ability to freeze the time of day

Example: Rallying
