Paladin spell coefficients for Attack Power and Spell Power

[Ralicx]

I was doing some preliminary testing on how different paladin abilities scale with regards to attack power and spell power. During my testing I came across some very odd behavior for particular spells, not only in regards to the scaling but also with regards to mismatches between the tooltip description and observed behaviour. Seal of righteousness is particularly fubar with some ranks scaling with ap and other ranks not and the tooltip info being completely out of whack (yes I tested with different weapon speeds).

Is there anyone who knows or anywhere that documents the actual coefficients the spells and ranks use for this server? I could not find this info on the database or forum.
