regulating philosophy

 Ed,
 
IT, for me is let-off and drop occuring at the same time, and very close to the string, with a very small amount of aftertouch.  I feel the click, see the drop (1 mm or so).  I like to barely feel the hammer check, because it happens so quickly (close to the strings).
 
Order of importance:  letoff/drop/aftertouch all about the same because without any of them, the others can't happen correctly.  Dip can't be too far off, but I would put it behind the others, right next to blow distance.  
 
It isn't about measurements per se.  They are only a guideline, not the holy grail.  It's about how the action feels, and whether or not everything is working the way it's supposed to.
 
Others with far more experience with high end pianos will chip in on this one, I'm sure.

I'm curoius to hear about people's approach to regulating. More specifically I'm looking for thoughts in two areas: 
 
1) When you are beginning to regulate using a few sample keys to discover what specs work best for that piano, what exactly is IT that you are looking for? How do you know when you have found IT? 
 
Is it more in the "feel" that a certain combination of specifications gives a keystroke, or is it more in the absoluteness of the numbers (for example, if you are looking for .045" aftertouch, then whatever combination of the other variables that results in .045" aftertouch is best)? 
 
2) As you work toward finding the best possible regulation you have to make compromises along the way. How do YOU rate the variables in a keystroke's geometry in terms of importance? For example, in the following list which items do you think take precedence over others: 
 
Blow Distance, dip, let-off, aftertouch, checking distance, (add whatever else I've missed) 
 
A curious mind wants to know. Thanks. 
Ed
