    "data": {
        "note": "Stand off-centre and the two halves carry different tensions: the horizontal pull is the same on both sides (H = weight × a × b ÷ (sag × span), with a and b the distances to each anchor), but the shorter, steeper segment runs at the higher tension because its angle is steeper. The short side is the one that fails first — which is why a highliner near an anchor stresses that leash and anchor harder than one standing in the middle.",
