Greetings, 
   I suppose I am one of the "different" people.  I like to set my aftertouch 
by using the fall of the hammer from the jack, rather than the first contact 
with the let-off button.  The latter is too easily confused with the drop 
leather making contact. 
    A maximum of .050" is my limit for aftertouch, but that doesn't tell the 
whole story.  Consistancy comes from the amount of pressure that you use to  
determine this dimension.  A firmer pressure is more consistant, so keep in 
mind what you are doing.  Using a .050" spacer and very firm pressure may 
produce about the same aftertouch as a .020" with a very light pressure.  
   This is done about midway in the regulation procedure.  Obviously, the 
balancier, let-off, hammer line and key level have to be finished. After the 
aftertouch has been determined, the final backcheck height must be set, which 
then allows the most refined approach to setting the repetition springs.
