The locations of the lap time and split time (middle or bottom of the display) in the

BEST indicator will not be transferred to the record with the next best lap time. See
“Memory Management” for more information about automatic deletion of records.

The unit of measurement used for the distance calculation depends on the unit you
select for your stride length as shown in the table below. See “To configure your
basic data” for more information.
