Do you have to have a TLE in the race SIs for the PRO to execute a Mercy Killing? Do you have to finish the laggards at a mark... or can you just finish them up the course.
A race ends when the time limit (if any) expires, when the last boat finishes, or when the race committee abandons it. Race committee may shorten the length of a leg (change course), or shorten course (finish the race at a rounding mark). The racing rules have no other provision for taking finishes. If you want to assign positions on the water, the procedure must be in the sailing instructions.
RE... starting the last race and then quitting for the purpose of banking some points... I put this behavior in the gamesmanship category...
Taking an advantage within the rules is not necessarily unsportsmanlike.
