basic regulating question

[mccleskey112 at bellsouth.net]

It seems to me that I read some where that a well timed action gave the perception that the key bottoms out exactly  when the hammer reaches the string.  If that is true then it seems to me that that would be our ultimate goal in regulating. Regardless of the numbers. Am I wrong?

         I have found that artists a FAR more sensitive to let-off 
irregularites than they are slight changes in keydip.   If I had to alter 
anything to 
make the after-touch even while keeping the same key-dip, it would be the blow!  

But I submit that keydip is less important than aftertouch. 
      At the very top of the line regulation, I alter keydip AND blow so that 
aftertouch is identical.  When doing this, I first set the keydip to a static 
value and make sure all keys are equal.  If, with an consistant blow, I have 
unequal aftertouch, I will move the keydip as much as .010" and the blow as 
much as .060" from the predetermined specs.  The effect of splitting the 
difference like this,(between the dip and blow)  is to make all the 
irregularities 
fall below the threshold of even the most sensitive pianists.  
    I have never seen any pianist notice .010" difference in keydip if the 
aftertouch was even, but I have been called back for having less than 1/16" 
difference between let-offs, (Ronnie Milsap is able to tell instantly if the 
let-off is not exactly even, but he never noticed the slight difference in dip.)
