We run the short course cars and the long course cars on the same course, so
some cars will complete thier run at the 3 mile and exit the course before
the 4 mile. We also run 150 CLUB cars on the same course, they complete
thier run at the 2 1/4 light then exit the course, most before the 3 mile.
Happy calculating.
