The 5% result out of switching out 2 Assault + (13%) for the two Phoenix weapons (and Pride is still a bit away). 26% - 21% (Phoenix Bow) = 5%

You are right if you count them seperatly, but in this case I was considering them as a pair mainly. And I also said, depending on your own Grid and probably what your Hime-Roster has to offer (I wasnt blessed with many defensive type Hime, so in order to not get constantly onto the brink of death I need some more HP to pull through).
