Scratch — A5.3 starting-area scoring with start check-in data

RRS A5.3 (alternative): DNF, OCS and similar codes score the number of boats that came to the starting area plus one. DNC (did not compete) always scores series entries + 1. Race 2 has only 3 boats checked in to the starting area: starting-area penalty = 4. Series entries = 5: DNC penalty = 6 regardless.

Scoring configuration: No discards. DNF/OCS scoring: A5.3 (starting area).

All 5 boats finish cleanly
    Only Alice, Bob, Carol come to the starting area (startPresent: true).
    David and Eve do not appear (implicit DNC).
    Alice gets DNF, Bob gets OCS, Carol finishes 1st.
    A5.3: starting-area count = 3 (boats with startPresent=true) → penalty = 4.
    DNC (David implicit, Eve implicit) still scores series entries + 1 = 6.
      David ("404") has no record — implicit DNC, scores 6
      Eve ("505") has no record — implicit DNC, scores 6
Points summary (starting-area penalty = 4, series-entry penalty = 6):
  Carol:  3 + 1 = 4    (3rd in race 1, 1st in race 2)
  Alice:  1 + 4 = 5    (1st in race 1, DNF in race 2 — scores starting-area penalty)
  Bob:    2 + 4 = 6    (2nd in race 1, OCS in race 2 — scores starting-area penalty)
  David:  4 + 6 = 10   (4th in race 1, implicit DNC in race 2 — scores series-entry penalty)
  Eve:    5 + 6 = 11   (5th in race 1, implicit DNC in race 2 — scores series-entry penalty)
