Er, wait, you found the Clear muted in the upper mids compared to the Elex? I would have expected the Clear to look, um, "wilder" than the RS2e in some of these results, and to think the Elex might sound less muted in the upper-mids than the Clear...I'm already cringing a bit. Agreed, the Utopia would probably be an interesting one to test. It had some peculiar characteristics that might shed more light on things. It's curious, you find the Elex can be difficult with its attack, and yet these visualizations make it look pretty well behaved compared to the RS2e...At least in the last two frequency results. But it seems we'd both agree the RS2e might be easier to listen to, if nothing else because it's slightly dark in some ways. Which, speaking of, I don't hear a lot of crunch or other weird effects on the RS2e. It sound surprisingly subdued, polite, possibly even dull in some regards. I'm not sure I hear it as unmistakably Grado in the highs, though my relatively limited exposure to Grado compared to some means I'm less qualified to make this statement. Nonetheless, it makes the HD650 sound sprightly in the highs, at least. (May be an extreme case of fat head syndrome.) But, yeah, I totally understand the goal here is the opposite of "one measurement to rule them all." More a matter of seeing if we can fill in those mythical subjective and objective gaps, including all the confusion, doubt, excitement, and sometimes seemingly contradictory data that comes with the territory. And no measurement of any kind will be a total match for all listeners. It takes time to process and integrate what these might mean, as you said, including what you, as an individual listener, might have to decide doesn't really follow what you hear. Even fat head syndrome can make for some interesting discrepancies in select cases.
