Good on posting a video demonstrating the idea. Well, my response to this would be the following:1. You very much have unusually large hands. Nowhere was it written that Chopin had saucepans for hands, and so why would he compose something he couldn't play himself? At a full stretch, you might even be able to stretch a thirteenth from what I see, and that is not average.2. You manage the tenths alright, but struggle with the elevenths. The problem is not in the stretch, but the evenness. Your descending runs, especially in the wider stretch, are very uneven, and the inner fingers clump together. This is because the extended hand position doesn't facilitate fluid movement since it restricts your ability to move those fingers downward.3. You are noticeably struggling with the two easiest arpeggios of the Chopin etude, and struggle to get any sense of consistency when it comes to those, to play without flubbed notes and so on. Extended to the entire piece, that would make for a very shoddy performance.
Interesting. Isn't this is opposite to what was observed when Chopin himself was playing this piece? I don't remember the source, but the observer described his right hand motions as opening and closing rapidly.
That would describe what is appropriate. The hand needs to strive to remain at naturally relaxed position when playing to promote a relaxed hand and Chopin would encourage this too. This paper might be of interest exploring many ideas of relaxed playing. https://www.researchgate.net/publication/336577947_Expressive_gesture_and_structural_disambiguation_in_Frederic_Chopin's_fingering_indications_A_preliminary_study_through_selected_etudespizza tower

Hmm...Seems like yet another "armchair technician"......Can he actually deliver?
Can you deliver? It's easy to go online and find excellent performances of Chopin 10/1 by concert pianists. Slow the videos down and you invariably see the "ugly, inelegant, inefficient technique" you complain about, and yet they look comfortable and sound great. All you've offered in your support is half a bar in the right hand from the etude. It's not unreasonable for people to be skeptical that you've found a better, more 19th century-ish technique, if all we've got to see is a couple of not particularly fluid arpeggios. So, go ahead and deliver a musical performance of the etude and you'll have a better chance at convincing skeptics.
I agree. Remain hands at naturally relaxed position will help to avoid hand fatigue. The article is so useful and informative. Thank you for sharing.
