Gun Fire Control System Upgrade Question

[vit12345]

Don't know if this question is asked yet but: Does the Gun Fire Control System upgrade improve the overall dispersion of a ship's guns? not the 16% range extend equipment but the researchable one. I noticed that for example the Kongo: the upgraded FCS gives 10% extended range at the cost of only 6% bigger dispersion at maximum range (237m vs 212m).

 

Need some clarification because at higher tier, I might as well skip the upgrade to save exp for hull/engine in case it does not give a noticable improvement on the dispersion.

As far as what I've noticed, it doesn't seem to help dispersion just increase range, but that's what I've noticed Tier 6 and below.

 

Someone else might have tested that out more though.
