RRS A8.1: The series scoring instructions state how many races may be discarded. Threshold stepping: once 5 races are sailed, 1 discard applies; once 9 are sailed, 2 discards apply. Alice wins 7 races but takes DNCs in races 8 and 9. With 2 discards, she drops both penalties and nets just 7 points. This validates that the scoring engine applies 2 discards (not 1) at the 9-race threshold and correctly marks both of Alice's DNC races as discarded.
Scoring configuration: 1 discard from race 5, 2 discards from race 9. DNF/OCS scoring: A5.2 (series entries).
Races 1–7: all three sail; Alice wins, Bob 2nd, Carol 3rd.
Races 8–9: Alice does not race (DNC); Bob wins, Carol 2nd.
Alice absent — implicit DNC (N+1 = 4 pts for a 3-boat series)
Alice absent again
Point totals (N+1 = 4):
Alice: 1×7 + 4×2 = 15 total. Drop both DNCs → net = 7.
Bob: 2×7 + 1×2 = 16 total. Drop two 2s (earliest first, races 1 & 2) → net = 12.
Carol: 3×7 + 2×2 = 25 total. Drop two 3s (races 1 & 2) → net = 19.
Alice leads in all scenarios (her 7 wins outweigh the 2 penalties even before discards).
The focus here is on confirming the threshold steps to 2 discards at 9 races and that
both of Alice's DNC races are marked as discarded.
