RRS A9(b): redress score is the average of the competitor's scores in races sailed before the race in which redress is granted, rounded to the nearest tenth (0.05 rounds up). 3 competitors, N=3, DNF score=4. Alice (sail 1) fails to finish race 3 and is granted redress under A9(b). Races before race 3: race 1 (2 pts, 2nd), race 2 (1 pt, 1st). Average = (2 + 1) / 2 = 1.5 → rounded to 1.5. With A9(a) the pool would include race 4 (2 pts) giving avg (2+1+2)/3=1.7 — different. Final: Bob 5 pts (rank 1), Alice 6.5 pts (rank 2), Carol 11 pts (rank 3).
