All-time best lap
ATBEST
The all-time best lap (
is the fastest of all timed laps
and is updated as soon as a
faster lap is timed.
The all-time best lap remains
stored in memory even if the
timed laps are deleted. This
means that other races can sub-
sequently be timed and the lap
times of those races compared
with the best lap from earlier
races.
The all-time best lap can also be
deleted from memory.
If the all-time best lap is from a
race timed in the past, it is ac-
companied on the display by the
appropriate lap number. If the all-
time best lap shows without a lap
number, this lack of a lap number
indicates that the time is from a
race timed in the past but sub-
sequently deleted from memory.
