“The detector” is not a machine for “measuring the amplitude”. In fact, we have no way of “measuring the amplitude”. The only tool we have “measures the ratios of the squares of the amplitudes”, and that tool is this: “run the simulation a bunch of times and compute the ratio of detections at 1 to detections at 2”.
