Accuracy Rating question

Does Masteries
"50% More Accuracy rating at Close Range"
"40% More Accuracy rating against Unique Enemies"
"50% More Accuracy rating against Marked Enemies"
Work for accuracy stacking setup?

If not - why? Description is VERY clear on "More Accuracy Rating", not "More Accuracy" or "More Chance to hit"

From what I know the more% don't work with the accuracy stacking boots the main source of accuracy stackers flat damage. I think it has something to do with the character sheet but who knows really. I think it might still work for other parts of accuracy stacker but I haven't tested that.

What is the mod that is stacking off the accuracy exactly? Those mods are conditional mods. The skill might be using the accuracy on the character sheet rather than being dynamic for each condition.

For example the Jug attack speed mod I assume, can only use one value for the attack speed per attack, as apposed to the accuracy roll of each separate enemy. It wouldn't make sense to be attacking at different speeds on the same attack, so I think It would use the character sheet value and not the conditional mods.

Those mods are conditional mods.

Then why Accuracy Rating on character sheet does not change, when those conditions specifically for Accuracy Rating - are met?

These mods apply to specific enemies, increasing your chance to hit them, but they do not change your current accuracy rating.

Wording of mastery says otherwise.
Why it doesn't work same way, like for example Solaris Pantheon bonus, that gives 1% phys mitigation? It does change character mitigaion on character sheet.
To be honest - i'm not even sure - these masteries work at all
Thus the reason - i posted this thread in Technical Problems, but it was moved to Gameplay Help And Discussions
