Is This Really Meaningful???

Unless I'm misinterpreting this graph, it's based on an amplifier that produces 10% 2nd harmonic distortion with no GNFB at all. How is that relevant to modern amplifiers? If someone intends to make a legitimate argument against feedback, maybe they should start with a 1% amplifier. I suspect the modest increase in higher harmonic energy that occurs when 10-20dB NFB is applied will then be at levels no human can be proven to hear.
