The problem here, as I've written previously, is that things that are difficult for some will not be so for others. Then there's the question of mechanical / hand/eye co-ordination difficulty (which is usually what's referred to in such discussion) as distinct from musical / interpretative difficulty. It's a minefield, for reasons including but not limited to those.

Thanks for your insight.
My view: Well, that's why I'm not considering an objective kind of exercise. I understand the opinions of people will differ as to the difficulty of the music, but statistics will still end up saying something useful (or at least informative) imho. If Chopin's octave etude, for instance, is considered by 49 out of 50 pianists to be his hardest etude, than that 1 person probably had an unusually good octave technique.
I think both ahinton and ranjit have useful ideas here. Actually, the whole issue I have is that the discussion of difficulty of repertoire necessitates what I feel to be a useful and interesting discussion, which tends to leads to talks on how these difficulties are handled, why one person think it is difficult for him while another does not, etc.
Furthermore, more significantly, I have not yet seen a convincing argument that negates the essentiality of how hard a piece is to its reputation. Why does the Alkan Solo Concerto or Rach 3 get mentioned a lot? Are they more beautiful or transcendental than any of the Beethoven or Mozart concertos? Maybe not. But it's because they're "hard". And it brings a sort of excitement to viewers if one would be the first pianist to play, for instance, the Alkan Concerto, because viewers are wondering whether he will give a masterful performance DESPITE the difficulties involved; the triumph appears greater since the piece is knowably difficult.
should have written as well that I disagree with the initial thesis that the essence of musical performance is the human feat of performing something difficult to play.
This is not the essence of any performance I would want to attend or listen to the recording of; rather the essence of a musical performance is to hear beautiful music performed so that it stores the soul.
If I merely want virtuosity and a technical feat, I’ll attend the circus and watch the high wire act. It frankly doesn’t matter to me if I am the only one in the world that feels this way, but I find it disheartening that a performance major graduate sees it differently.
If I thought learning to play was only as a technical feat, I would lock the fallboard
I never said it was the "ONLY" essence, but it's still a component of it. Why then, are many familiar with that famous story of Dreyshock playing the Revolutionary in octaves? Or Chopin's Minute Waltz being turned to thirds by Rosenthal? Or Cziffra's version of the Bumblebee? Does it make them more musical? Not necessarily. But it DOES make them sound more "impressive", which is the point.
Then there is Liszt, who famously started the tradition of playing the piano sideways for audiences to see him. I even think it's to see his hands. Whenever I listen to some of his early bravura pieces on audio only, I always think, "it's not that interesting to just hear. I think these were composed to be SEEN". These pieces just aren't going to be that effective unless the audience sees the flying hands of the pianist, which Liszt seemed to have understood, and aimed for. Does it change, in anyway, the music (sound)? Of course not. But the visual appeal - the stunt work - is taken into account.
One goes to hear music mainly because of the enjoyment and emotion it brings, but there are times when one is curious about it partly because it is so hard and he'd like to see how far the pianist goes.
Don't get me wrong here: Again, I never said I listen to music because it is difficult. I sometimes do, sometimes don't. It's kind of part of the package. It's that feeling of surprise and shock you feel when you see Oscar Peterson go into a frenzy improv, or Cziffra do a cascading run that sounds like rockets being shot into the sky; it sounds impressive, and it is an impressive feat.
