I finally had the opportunity to put this to use.  I needed to cut some 15/32 inch dadoes to fit what supposedly is 1/2" plywood.  Following the guide on the case insert, I stacked the left outside blade, a 1/16" spacer, a 1/8" chipper, the .020" & .012 shims and the right outside blade.  I set the height and fence and proceeded to make my cuts.  The results in poplar were excellent.  The dado width was spot on and the 15/32" plywood fit into the dado beautifully.  The edges were perfect and the bottoms were flat.  There was minuscule tear out when exiting the dado (maybe a half dozen wood fibers not cleanly cut off).
