I think this is about as good as it gets. No matter how I adjust my FD I still get a slight rub on the third smallest cog (14T) which is only apparent when riding, not while my bike is on the stand.
Interesting that the manual (DM-FD0002-05) for the FD-9000, FD-6800, FD-5800, and FD4700 shows a similar picture as what
shelbyfv posted above but only grays the 3 (not 4) smallest cogs.
