"note": "Total drop = twice the distance above the last piece, plus slack, plus the rope's stretch (≈10 % of rope out under a hard catch). If that exceeds the clearance to the ground or a ledge, you deck. Low first clips, minimal slack and an attentive belay are what keep the margin positive — count the stretch in, especially near the deck.",
