Critical Hit Calculations?

I am so incredibly confused by this.


Under the critical hits section of your character's info screen, there is a "Main Hand Critical Hit Chance" and a "Estimated Main Hand Critical Chance from Hit Chance."

For me i'm at 11.4% crit chance and critical chance from hit chance is +62.7%.


For your final crit chance....do you...add these numbers together?! IT doesn't feel that way.

OR, do you had 62.7% of the 11.4% to the 11.4% to get your final chance?
