If the protest committee decides to give redress by adjusting a boat’s score for a race, it is advised to consider scoring her
  1. points equal to the average, to the nearest tenth of a point (0.05 to be rounded upward), of her points in all the races in the series except the race in question;
  2. points equal to the average, to the nearest tenth of a point (0.05 to be rounded upward), of her points in all the races before the race in question; or
  3. points based on the position of the boat in the race at the time of the incident that justified redress.
