Sometimes it is hard to make out where the maximum is on the 3D plots. 
It is possible to also add a contour diagram in the x-y plane to help
with these visualizations and determinations.  I have included a
slightly modified version of the file I sent you before (that I will
place on the class website) that includes the projection of the
megaflops onto the x-y axis.
