Then, I might also add, that it's impossible to 
do springs - precisely or otherwise - before 
getting the backchecks fairly close, because 
backcheck regulation affects spring compression - 
and therefore the speed at which the hammer 
"jumps" when you test the springs. If backchecks 
aren't at least close to where they ought to be - 
you will be getting a false reading on how strong 
the springs really are. The gist of all this is 
that you pretty much have to get all your 
regulation points or functions "in the ballpark" 
before attempting to regulate anything precisely. 
It's sort of like doing a pitch raise before fine-tuning.

What you write below, Larry, is probably one of 
the best statements of how regulation actually works that I have seen.
