Your problem -- whatever that is -- is not with the piano.
It is with your mind.
By now, you should not find it necessary to obsessively dissect piano technique the way you do.
You should be able to think of what it is you wish to express and go about doing it.
I was reading a bit on the internet and ran across old posts from you arguing with Alan Fraser several years ago about THE VERY SAME THINGS!
He did not agree with a good deal of what you said, though he was very polite about it, and as usual you basically said he was wrong.
This is your modus operandus, i.e. to attempt to elevate your appearance of competence by attempting to dissuade or out right "debunk" the opinions of others if you have the slightest inkling they don't concur with you fully.
This has never worked for you, doesn't work, and never will, and yet you persist?
I'm fairly certain, the participants in this thread would agree that you WAY over think everything, and this is not superior at all, but keeps you stuck.
So your problem is mental/psychological, and I do not mean this as a put-down: I was stuck in a similar "pianistic hell" when I was much younger of being determined to figure everything out and understand everything, and thank goodness I was able to mature and "outgrow" it.
For some reason you have not.
Not only is it NOT necessary to figure everything out about piano playing physics, it is NOT POSSIBLE.
And yet you persist -- and this in spite of indications from others that you are on the wrong track.
This is why I say your difficulties are mental/psychological.
So what is the way out?
To begin trusting yourself, let go and silence the voice in your head.
Just practice and play the piano and try to move beyond the novice state of "having to know everything".
This will be extremely difficult for you, I suspect, as I found it difficult, though you have a worse case of "piano mechanics obsessive disorder" than I ever did.
I'm saying this in this public forum, since all that you have said and manifested has been public, and perhaps with this awareness you can ask others about their opinions since they're aware of what's going on with you and offer help/insight.
With this in mind, I think communicating with you in terms of "mechanics" is not at all helpful, so I think I'm going to confine my future exchanges with you to musical issues.
I hope you find your way out of this maze.
