OK, How about we score it like Figure Skating, throw out both one low AND one high score? After all, the high score might have been due to pure luck, a flyer to the corner, lucky wind shift, etc. while the other faster guys went to the wrong side of the course.
In a low point scoring system, just throwing out
the best finish along with the worst only further
rewards bad sailing. Throwing out the best and the
worst only works if you average the scores.
Can of worms, that.
