Whew! I started reading that thinking I was going to have to REamend my assesment - but thankfully no, I finally got it.
I am, however, interested in how the last part of that rule could ever happen after sorting as per the previous two directives:
(b) If there is a tie in series scores between two or more boats, each boat's race scores shall be listed in the order of best to worst. At the point where there is a difference, the tie shall be broken in favour of the boat with the best score. If a tie remains is shall be broken in favour of the boat that obtained her best score nearest the end of the series. If a tie still remains it shall stand for the series results, and boats tied for a prize shall share it or be given equal prizes.
