French experience reduced quad-turret accuracy problems

Did French quad turrets suffer accuracy problems like Italian close-set guns?

They had issues, but France had experimented with quad turrets longer than most navies and had already worked out most of the problems.

French quad turrets had accuracy problems and were not perfect. Most of those problems had been worked out. France's longer experience with quad turrets gave it an advantage because designers had already encountered many of the mistakes involved. That accumulated experience matters when comparing the French mounts with the Italian accuracy problems raised in the question.
