       You bet and I would consider an action ratio mated to a key ratio to 
be the best way to go to achieve this. (You'd think this would be  standard 
O.P in factories.)  This is what Rick Wheeler at Roseland on is doing on new 
keystets and what David Love and others are doing when  moving capstans and 
choosing hammer shanks and appropriate knucle geometry in existing actions.
    I read Bills post and though it's not news to me I think intuitevly  
accomplish the same thing by feel. Basically I use .390 as my target 
/ballbark desired dip spec.(measured at the pin) but I do the aftertouch feel 
by tactile sense,which will vary the dip slighty to allow for the 
descrepencies in action accuracy. Especially with new felts and action parts 
, set regulation specs move around a good deal as we all know so in the round 
robin approach to regulation I have always checked very carefully the blow 
and let-off before I get completely obsessive about dip/aftertouch. 
Compliments of Red Schoolhouse theology, I mean technology.
