Tennessee refit five-inch gun arcs

What are the advantages and disadvantages of the five-inch/38 arrangement on the refitted Tennessee-class battleships?

The arrangement lets multiple mounts bear across broad approach angles, giving strong volume of fire against aircraft even if the bow and stern arcs remain tight.

The refit's value lies in its gun arcs as well as the added battery. The middle pair could fire over the outer pair, letting the ship bring several five-inch guns onto likely approach angles and create enough fire volume to matter.
