RRS A5.3: A boat that did not start, did not finish, retired, or was disqualified shall be scored points equal to the number of boats entitled to race plus one (N+1). With 5 entered boats, N+1 = 6. A boat absent from a race (no finish record) is scored DNC = N+1.
Scoring configuration: No discards. DNF/OCS scoring: A5.2 (series entries).
All 5 boats finish cleanly
David gets OCS (on course side at start), Eve DNF (retired mid-race)
Alice, Bob, Carol finish normally
Carol has an explicit DNC (decided not to race)
Eve is absent (no finish record) — treated as implicit DNC, same score as explicit DNC
Eve ("505") has no entry at all — implicit DNC
Points summary (N+1 = 6 for all penalty codes):
Alice: 1 + 1 + 1 = 3
Bob: 2 + 2 + 2 = 6
Carol: 3 + 3 + 6 = 12 (DNC in race 3)
David: 4 + 6 + 3 = 13 (OCS in race 2)
Eve: 5 + 6 + 6 = 17 (DNF in race 2, implicit DNC in race 3)
