Peak performance 5? Am I cooking?

I got a 3rd level of Peak Performance on Anja Greaves as a meme but I realize since I don’t need max focus on Jho Bow, I essentially have Peak Performance lvl 5. If I use Burst 2 from Rathian Vamb. would this outweigh the loss in element from going dragon attack 3 and focus 3? I lose the dragon attack lvl 4 by subbing the Greaves for that last level.
