None of that has to do with Resolution, it's a page about ratio differences, and a changelog for those. The WS calculator on the left specifies nothing about specific weaponskill attack penalties.
What exactly are you looking at?
Edit: found the only page regarding weaponskills, it doesn't seem to have any information regarding attack bonuses or penalties.
Gobli itself doesn't have that information listed either. Only attack penalty information that I can find is mine from BG.
レゾルーション 攻撃力約-?%→緩和
edit2: nvm found what you were looking at.
レゾルーション 0.89? 攻-11%
Doesn't look like they have that value solidified. 3% difference in attack penalty is fairly large, I'll look over my data and do a few more tests when I have time.
