Jim,
I am not sure I understand, perhaps I am reading these postings wrong.  I 
have always worked the relationships between key dip, aftertouch and hammer 
travel as a compromise to get the best results within certain parameters.  
That means I may fudge a little on hammer travel to to get the right touch.
I also measure the hammer travel from the back of the moulding and will get 
different readings from a new hammer than one that has been filed.  The 
shorter the hammer the longer the distance it will have to travel from the 
same starting point to the string.
