Sigma?

I'm just putting out something that's been niggling at me for a while and that is how valuable is sigma really? I've seen people saying time and again that Ashitaka and Kii are both handicapped by their dispersion, but I've personally never experienced a problem. And then there's the NC which has a sigma of 2.0, but I swear that some times it struggles to hit water; meanwhile I just picked up the Mass and despite hearing about it being less than accurate, in my first game my shots went exactly where I wanted them to. So does sigma really play that much of a role in dispersion?

Sigma is a roll of the dice for good grouping. In other words, NC will get more of those tight grouping moments compared to Massachusetts. Just because Massachusetts has bad sigma doesn't mean it can't get good dispersion, it just has to hit that 1.7 sigma luck for that dispersion.

has literally the worst dispersion and sigma of any ship at tier.

Massachusetts should have the same max dispersion value as the Alabama and NC, it's just the sigma that's different. I pulled off tight groupings from Massachusetts from experience, just got to sling enough salvos for that 1.7 sigma to work. The poor sigma is made up by its secondaries.

yes and they also have the worst dispersion in the game. they however do not have the worst sigma at tier.

Sigma is a reasonably good indicator of accuracy, but it's not the one defining feature of it. Horizontal and Vertical dispersion are very important as well, as is the shell speed.

I thought Sigma was vertical dispersion.

Sigma just determines how likely your shells will end up at the center of where you are aiming, vertical dispersion is affected by sigma by it's not it.

I was always under the impression that Sigma is how much of your salvo will be weighted towards the center of your aimpoint and Dispersion is the maximum size of the ellipse that those shells will land. 
I was also under the impression that vertical dispersion is more affected by velocity than sigma or otherwise

The "ellipse" where your shells would fall is defined by the horizontal and vertical dispersion. Sigma is how tight those shell grouping are from the center your aiming point.
