This can be useful in following situations ... :
- forgotten to SHORTEN course and boats are showing as 'still racing' ... or
- ABANDONED the race and want to take the results from a PREVIOUS completed lap
[if you want to just correct and mistaken shortening of the course use the Undo Shorten Course button on the timer page]
Set the finish lap for each fleet to the lap you want the boats to finish on (i.e. the laps for the finish of the leading boat).
