HalSail RDG type 2: the redress score is the mean of the boat's points in all other races, but DNC results are excluded up to the number of races the boat may discard. If it has more DNC results than it can discard, the excess stay in the mean. 4 boats (N=4, so DNC = 5). 4 races scored → 1 discard allowed. Alice is granted redress in race 4. Her other races: R1 = DNC (5), R2 = DNC (5), R3 = 2 (2nd). One DNC may be excluded (discard allowance = 1); the other remains. Pool = {5, 2} → mean = 3.5. (Plain RDG type 1 / all_races would average all three: (5+5+2)/3 = 4.0.)
Scoring configuration: 1 discard from race 4. DNF/OCS scoring: A5.2 (series entries).
Points (DNC = 5; discard the single worst score):
Bob: [1, 1, 1, 1] total 4 discard 1 → net 3 (rank 1)
Carol: [2, 2, 3, 2] total 9 discard 3 → net 6 (rank 2)
Dave: [3, 3, 4, 3] total 13 discard 4 → net 9 (rank 3)
Alice: [5/DNC, 5/DNC, 2, 3.5/RDG] total 15.5 discard 5 → net 10.5 (rank 4)
