I don't know much about this but what I read.
You want to consistency have high finishes. Tenth or better. Paul Goodison had mostly better than 6 until the last race. He may have been messing with only one that had a chance to win the championship in the last race.
So do a conservative start. Toward the center away from the ends, but toward the favored end.
Sail fast. Work the shifts and get to the favored side if there is one.
If you are not leading, pass boats on the run. If you can't pass boats on the run, then back to school for running.
Then in the last race you may have to match race in the fleet or just make someone else take a throwout with you.
