Elemental Weakness Questions

If someone can fill me in on how the following scenarios works:

Paladin dual charges A + B and attacks a mob.
A Strong + B Weak:
A Strong + B Neutral:
A Strong + B Strong:
A Weak + B Weak:

Also, the same scenarios except the mob is Physical Strong (Pink Bean).

F/P Mage attacking Pink Bean with maxed Elemental Decrease.

Battle Mage attacking Pink Bean.

Elemental reset removes the element of the skill you are using INCLUDING physical element so the f/p would do its normal dmg on all mobs. Any skill that does not list an element in the extractions is physical element so a BtlM would do 1/2 dmg to phy strong mobs. (I have tested this against the fairy queen)
