Nor do I.

Yes.

Yes.

More below.

Yes...and, some of them want to feel the engagement of the jack tender and 
drop screw as two separate events, while others will be made crazy by the 
same sensation.

Agreed.

Cherkaski was an interesting fellow to work for.  He had very specific 
requirements which were not always well communicated.  He was, for example, 
much happier with a quite shallow key dip and very limited touch.  This, 
combined with a preference for a somewhat glassy sound, made it difficult 
to get the piano exactly as he wanted it without making too much trouble 
for yourself with the very next pianist.  (That being said, I did love his 
playing...even as highly stylized as it seemed to me to be.)

Sounds like an all-too-familiar kind of rotation of people coming 
through.  Ms. de la Rocha was from another school of performance 
altogether.  While she also had an increasing preference for brighter 
pianos (especially later in her career), she really did prefer something 
that she could "sink into".  That seemed to translate into an action with 
more "feel" too it, overall.  She was, you will recall, a specialist in 
Spanish music; and was immediately aware of repetition issues that many 
other pianists would not even notice...therefore, she was acutely sensitive 
to the depth and consistency of touch, especially after-touch.  A few minor 
variations were tolerable.  More than a few were simply not.

>I do know what I am talking about and I have been around for some time.

Understood.

Precisely the point.

The issue of is one of control, or, more precisely, the perception of 
control.  And, this is where the technique, or lack of technique of the 
pianist becomes a crucial issue.  And, it is also where technician so often 
miss the mark in becoming so wrapped up in reductive analysis that they 
lose sight of the equally important intuitive perceptions of how a given 
action/instrument might be.

 From a certain point of view, it is rather like tuning an L with bad bass 
strings.  Between the odd shape and size of the board, the placement of the 
bridges, etc., the bottom 6th of those can be pretty difficult.  Add in the 
bad set of bass strings, and there is so much going on - which is to say - 
so much reductively analyzable data immediately available, that one can get 
quite turned around.  On the other hand, one can approach the same 
situation from a more wholistic standpoint, and come up with an at least 
marginally usable instrument.

All of which is to say that these issues are matters of perception; and, 
subsequently, matters of communication.
