What sticks out to me about the subjective/objective thing is things like the Magnepan LRS speakers which I and many others have and love yet measure poorly on ASR. Are things like image size and room reflection dynamics of dipoles etc things that can be measured. Can we show some objective measured thing that explains why many like the Maggies. I think this is where the measurement approach fails.
The LRS was both measured by me and by Workwyn for AudioExpress with the same results. Speaker beams heavily creating a very narrow listing spot. In addition, it has little to no bass. These are facts enforced by physics of speaker design and there is nothing you can do about it:

The appeal of these dipole speakers is that they are basically effect boxes. The back reflections create a spacious sound that many audiophiles relish. I am not a fan because it overlays the same effect on every kind of music. This becomes tiring to me as I don't expect rock/pop tracks to sound this way. Ditto for the tall image their portray.
But again, I know the appeal. I know that with a ton of fiddling and room manipulation you can improve their sound. So no need to search for such proof. If you want a specialized speaker, they can be a good choice.
