   Well yes there is the obvious relationship that at the stepwedges %
X you get density Y. But the % value listed on the stepwedge isn't 
the relation it seems to be. That's creating the confusion people 
have been posting. At 50% on the stepwedge people were expecting 50% 
of the max density but it doesn't work that way.
