question on post-justice aran

I checked full swing and it actuallly lowers your damage at level 1, am i right?

Full Swing 1: Double Swing: MP Cost: , Damage: 167%, Number of Hits: 2, Triple Swing: MP Cost: , Damage: 437%, Combo Smash Damage: +12%

(167%x2)+ 437% = 771%

Double Swing 20 MP Cost: 5, Damage: 250%, Max Enemies Hit: 8
Triple Swing 20 MP Cost: 8, Damage: 500%, Max Enemies Hit: 8

500%+250%=750%


O_o what seems to be the problem sir
