Mr(s). IBTY:
I'm not sure if you tried to play it, beyond just looking at it. The problems begin there... I think that it is a very difficult piece of music, and desconsidering anything else, it lasts 40 minutes or more. In my modest opinion, these lenghty works are always a huge challenge, because in a recital you have to "fight" with your stamina and focus. Try to aim at a flawless performance of it and there is such a goal. Given the fact that it's a very deep and meaningful music, and "playing all notes" is just 50% of the work.
So, if you can play the sonata without blurs, with a consistent interpretation and still alive, my congratulations: I can't for sure.
You pointed out opus 111 as harder than the opus 106. May be. The former is far from being easy.
Best!
PS: would you mind to don't use these "da" and "dat"? It's a bit boring to read this way.
