Yes, I agree with that. On which features matter more for preference, maybe it depends on listening volume and/or listening duration. I will stay tuned to see if this will get a definitive answer, it's a good question. I would prefer the Hps.com preference bands to be based on the two curves here rather than what they are using now.That target (SoundGuys) also has approximately 3 dB less energy in the 20-70 Hz area per the above graph. Which of the two areas with the most difference matters the most for preference rating?
I think we could equally conclude that (paraphrasing): “One big thing I take from this is that a target similar to Harman IE 2019, except slightly less V-shaped and slightly more tilted, is statistically tied.”
