This might have been mentioned elsewhere, not sure. It is a pretty minor suggestion but one that should hopefully clear up some confusing terms.
http://fonline-aop.net/wiki/index.php?title=Critical_HitSo there is the "critical strength" which can roll between 1 and 6.
http://fonline-aop.net/wiki/index.php?title=Critical_StrengthThen there is "critical strength" which is a perk which is rolled specifically involving your SPECIAL strength stat
And the "Li Jing" leadership module which has a BB of +1.0 critical strength.
See the possible confusion?
Also, for the leadership one, I assume it is +1% chance to negate rolls which would involve the strength rolls, and not adding onto the power of the critical, nor is it adding 1 strength for determining that. It would probably be a good idea to clarify that in the pipboy, as well as the critical perception/agility/endurance modules.
