I am answering you seriously in order as well...
A it doesn't change anything for me whether you hit the notes or not, this discussion makes no sense even when playing Beethoven or Chopin or Mozart, everyone hits a wrong note; I was responding to whoever asked the question with a sensible answer, namely, groups of notes belonging to sets.
1) You haven't understood the meaning of what I wrote... Relying on a mathematical foundation ensures that what is proposed is not random. However, it is important to follow this mathematical algorithm to the end and make one's own choices before starting to write. Formality and coherence are based on this. Here, we lack coherence because even if just a single note does not come from the formality of the algorithm used, well then one can assume that the product is random. Example: if the Fibonacci sequence returns an ordered series of numbers that are THOSE numbers (0, 1, 1, 2, 3, 5, 8, 13, 21, 34...) even changing just one would make it lean towards a non-existent series, which is not the Fibonacci sequence and which we can assume to be stochastic, perhaps ordered, but stochastic e.g. (0, 1, 1, 2, 3, 5, 8, 12, 21, 34)
What I am saying is that perhaps even you don't know what you are talking about. You want to justify the criticisms made against you by saying there is a mathematical explanation behind it, you talk about recurrences without knowing where these recurrences are. The recurrences you speak of are all written in the score, phrase by phrase, but my opposition takes shape from before, from the base.
2) This is also not true; if you search the forum you will see that I spoke very highly of a Stockhausen study played by Pollini, a topic several months old, therefore what you wrote is a falsehood.
3) This sentence you wrote is very important and it is true that I support it and I will tell you more, I will continue to support it until someone proves me wrong. You have a beautiful musical culture so you cannot be taken as an example, but the proof of what I say is that when 30 posts ago I asked supporters to explain this score to me, all I managed to get was: "read this link". My request was obviously provocative; the fact remains that in previous posts I only heard: "I like listening to it, I don't like listening to it", no one motivated or argued their satisfaction / dissatisfaction, the only one to do so has been me so far and until proven otherwise. I would like to hear arguments.
Moving forward, I do not categorize this piece as simple at all, nor as the most difficult; my initial observation reporting the example of my cousin was referred to and aimed at the randomness of the notes. And I do not love a Random piece.

Look, I don't call it a battle against composers, I don't call it a battle against performers, and a battle against windmills. Each of you can play it, I don't consider it stupid, not at all; instead, it seems very intelligent from a certain point of view, I simply consider it useless. Even if it exists for history, if I don't listen to it and don't play it, for me it doesn't exist, that is a fact. The concept of a field is quite clear even in physics. Fields exist the moment there is a particle that experiences them. We are the particles: interpreters, composers, or simple listeners. Whoever listens to it experiences it; for them it exists, for those who don't listen to it, it doesn't exist. That is why it seems foolish to me, with all due respect, to try to convince me of the importance of something that, for me, does not exist.
