441 sailed hot angles that didn't pay — fastest SOG, longest path, slowest run. 298's lower mode wins the leg.

298 closes to 2.0 s at the finish — one more leg and the result flips.
Data quality: * 0 tacks/gybes — maneuver detection didn't run. † per-leg VMG/heel + start values illustrative. Race-scope SOG/Distance recomputed from legs — v2's race scope appears to repeat Leg-1 values (verify in engine).

NEW IN V3c

  • RACE OVERVIEW block first: rows Start · Legs 1–4 · Finish. Segment winner shows their time with ★; the rest show +Δ only. Answers "who won what" in one glance before you scroll into detail.
  • LEAD column = the progress story: cumulative margin over 2nd after each segment — 441 +2.4 → +16.5 → +15.4 → +7.3 → +2.0 → WIN. It's the lead-erosion chart as a column of numbers.
  • Start = who was off the line first (gun → line time); Finish = who crossed first (elapsed). Same time-based rule everywhere.
  • x̄ average column option demonstrated on the Full Race block: chips toggle x̄ Fleet / x̄ Selected / off. The x̄ column is muted and never gets best/worst coloring — it's a reference line, not a competitor. With larger fleets it works the same (you pick 4–6 boats via the magnifier, x̄ can be full-fleet or just your selection).
  • Magnifier top-right (design-standard lens icon) with a 3/3 selected-count — opens the fleet picker to choose which boats this whole report renders for. Every block, and the PDF, follows that selection.
  • Boat colors corrected to the design standard's FOCUS_COLORS: 441 azure · 298 amber · 181 coral (I had 298/181 swapped in v3b).

CARRIED FROM V3b

  • One scroll of same-shape comparison blocks; jump chips; sticky boat header; tri-color best/worst with tie rule; Δ vs leg best inside each leg block; leg story notes; data-quality flags.
