I thought of that too and really ran into a plethora of knuckle 
heights five years ago.
Not only are sets not uniform but other sets have different averages.

One set may mic at .620" ave., another .650", and another .640".  It 
seems to depend
on each knuckle set made and the consistency/degree to which they are 
pressed in.

One set was so bad, I had to remove the knuckles completely. I still 
have that set
of shanks because the previous tech installed the hammers at a 5" 
radius and angled
the hammers back.  Let's just say that the customer didn't like the 
sound and touch and
had the whole shebang replaced within five years.  There's another 
similar one which I'm
prepping for.

If a knuckle measures upwards of .650 or lower than .620, I'll reset 
the knuckle to fit
the set in progress.
