RRS A8.2: After counting first-place finishes (equal here at one each), proceed to count second-place finishes. Alice has two second-place finishes against Bob's one, so Alice ranks ahead despite equal total points and equal first-place counts.
Scoring configuration: No discards. DNF/OCS scoring: A5.2 (series entries).
4 boats, so N+1 = 5 (DNC penalty).
Alice: 1st, 2nd, 2nd, DNC → 1+2+2+5=10 (1 first, 2 seconds)
Bob: 2nd, 1st, 4th, 3rd → 2+1+4+3=10 (1 first, 1 second)
Carol: 3rd, 3rd, 1st, 2nd → 3+3+1+2=9 (1 first, 1 second — but lower total, ranks 1st)
David: 4th, 4th, 3rd, 4th → 4+4+3+4=15
Carol wins outright (9 < 10). Alice and Bob tied at 10.
Tie-break step 1 — count 1s: Alice=1, Bob=1 → equal.
Tie-break step 2 — count 2s: Alice=2, Bob=1 → Alice wins.
Alice gets DNC (N+1 = 5 pts); Carol 2nd, Bob 3rd
