The dispersion debuff without target lock is added primarily to protect “anti-dispersion” camo and related upgrades / captain skills from being bypassed by mods.

Camo / concealment upgrade debuffs and upgrade buffs are applied to horizontal dispersion at maximum range. The effects multiply, so shooting at camo target (x1.04) with Aiming mod 1 (x0.93) results in x0,96 to maximum range horizontal dispersion.Gameplay-wise that means these effects are growing with range and have almost no influence on CQC.

Your sigma count matters– while not influencing dispersion ellipse in any way, it influences the density if your salvos. Shells are being placed by Gaussian distribution, and sigma count affects it. The parameter may be tweaked per ship, but it is not very diverse. The base is 2.0. The more = the better. It is used in balancing. For example, Fuso has huge salvos, so it is set with 1.5, and BBs tend to have lower sigma count in general. T9-10 cruisers were systematically and gently buffed lately by giving them 2.05.

Now, just to be sure, these things DO NOT influence your dispersion in any way:

1.Your maneuver and speed.

2.Quantity of turrets firing a salvo.

3.Any game modifications.

Yes, this mechanics is complex. It was a challenge to design and implement, it is a challenge to describe and explain, but mostly, you don’t need to bother about it. It is here, and it works, allowing you to aim your guns and have fun. I hope I was able to highlight several nuances that matter. Sorry for any possible English issues

Good luck and fair seas!”

在不锁定情况下的散布惩罚主要是为了防止加大对面炮弹散布涂装与相关升级品或技能被mod绕过。

涂装，升级品和精度插的效果都是被增加到最大散布上的水平散布上。这些效果是相乘的，所以装了精度插(x0.93) 向对面一个用了涂装的(x1.04) 射击的结果就是最大水平散布x0,96。在游戏中这个效果会随着距离增长而且对CQC几乎没有影响。

你的sigma也很重要。尽管不影响散布椭圆，但是这个影响你的炮弹的落点密度。炮弹落点遵循正态分布，而且sigma值会影响这个。这个参数可以对不同的船做出不同的调整，但是这个参数也不是各种各样的。Sigma的基础是2.0。值越大越好。这个会被用来平衡。比如说Fuso的投射量很大，所以sigma是1.5，而且BB的sigma总体都比较低。9，10级CA的sigma被系统且略微地buff到了2.05

现在，需要确定的是，这些不会影响你的散布：

1.你的机动状态与速度

2.开火的炮塔数

3.游戏mod

没错，这些机制很复杂。设计和实装这个是一种挑战，描述与解释这个也是一种挑战。但是总体来说，你们不需要为此困扰。它就在这里，它就是这样发挥作用的，它允许你瞄准和玩得开心。我希望我指出了那些有影响的细微差别。英语表达有问题请见谅。

Good luck and fair seas!
