So tell me your opinion, if you don't mind, and any alterations.

Hope this is not confusing. I'd love to hear any thoughts you have on this practice/training phase and how it difers from what you do.
Sounds all right to me. I wouldn't change anything. The trick is to bring yourself in a state of full concentration on the RIGHT things, a state of letting it go, not worry what the end-result will be, and the type of movement in itself is not that important. The main problem during practice is that people start worrying, try to control too much what they don't need to control, etc. You have to find a way to get rid of that in the pieces you want to play.
As to my own movements; they are specifically related to my hands, that are huge and VERY strong (think Rubinstein). Trying to do any of my movements may get you into trouble, or may even affect your artistic self. First of all, I do all kinds of gymnastics away from the keyboard. I cannot possible give you a description; this is too personal.
At the piano, and to free myself from the physical and/or psychological limitations in playing:
For finger technique I lift them rather high and let them drop (swing them lightly, just enough to get a Lipatti tone quality) s-l-o-w-l-y, so slowly that nobody in the next room would even guess what I'm doing.
For octave and chord technique, jumps, etc. I lift my hands in the wrists and let them drop (swing them lightly, just enough to get a Lipatti tone quality) s-l-o-w-l-y, so slowly that nobody in the next room would even guess what I'm doing. NOTHING is fixed in the process, and I have all the time of the world. This works for me. As soon as I feel I'm ready, my mechanism carries out virtually anything.
I can imagine that you can reach the same state with movements N. is talking about. It's a kind of awareness without interfering. The movement itself is not that important. Main parameter: The movements should be comfortable for the one using them.
P.S.: How personal practising can be: Richter had a very peculiar way of practising: as loud as possible, and if necessary a hundred times in a row, get back to reading a few pages of "Moby Dick" or any other book he might be in the process of reading, and again one hundred times as loud as possible. This worked for him to free himself from the physical and psychological limits in playing. As you can understand, few could repeat that after him without hurting themselves seriously, because he really had an incredibly strong playing mechanism. Of course, the state of mind is to condition yourself for succes, for confidence in what you're doing.
