If the FD height is correct (3mm or less clearance between the outer plate and the big ring teeth at their closest approach), and the outer limit is adjusted to barely clear the chain when it's on the big ring/smallest rear cog, then the shift always works, and the chain isn't thrown off. Have you verified that the outer plate is parallel to the big ring when viewed from above? And are the rings facing the correct direction (the teeth are offset slightly).
I only have 8-speeds on all our bikes, but I believe that's the correct procedure regardless of speeds. Matching the components to the speed count is important in the front, since the spacing between the FD plates is critical with the skinnier chains.
