Question, how does each of these stats scale?

I assume STRENGTH increase the base physical DMG of a weapon by 5%. So a weapon at say flat 10, physical DMG would do 10,5 physical DMG with 1 point in STRENGTH.

One guy in a thread said that WARFARE, instead of yet again multiplying the base physical DMG with another 5% it would multiply (all) the already boosted physical DMG (boosted from STRENGTH) with 5%.
So it would give 11,025 physical DMG with 1 STRENGTH point and 1 WARFARE point. Instead of giving 11, physical DMG, which it would if it added 5% from the base physical DMG like STRENGTH does.

And how does Two-Handed work? Is that another 5% added of the base physical DMG?

Maybe there is a database that some one could direct me to that I haven't been able to find.
