Exactly.  We even have a jig that precompresses the balance rail 
punchings.  Those little suckers tend to compress big time in 50-70 hours 
of playing......then the action feels like s__t, because there's no 
aftertouch; I warn players that the action will start feeling strange 
when compression starts.  It's a great way to guarantee yourself a couple 
hundred bucks or so; you ALWAYS need to raise the key height on new 
balance rail punchings after a little while.  Always. A blue punching, 
and it's like magic----everything comes back into the ballpark........
