    "question": "Which lower monitor value has independent mass support, and can any load's readings alone establish a lower area-normalized yield?",
    "answer": "GY2's monitor falls to 80 while its independent scale remains 100, documenting a measurement disagreement after the setting change rather than a confirmed mass decrease. GY3's two sources agree at 70, supporting that load's lower measured mass. None supplies comparable harvested area, so these values alone do not establish an area-normalized yield drop. Preserve crop, moisture basis and load identity before attributing a map pattern to crop performance.",
