Oh, yeah, you confused me, too.
But you're confused on some things yourself. Your unit combination doesn't mean anything except what your (paltry) base stats are. They don't have any compatibility.
If you've done any resets/hell training on that record, then just keep doing it. You may as well run it into the ground since it's impossible to get a perfect producer evaluation if you do it even once.
If you're not using one of the voltage boost amulets, use those. The one from the capital area special festival is the better of the two, honestly.
Either way, I still think you're not doing something right. Capped stats and a good amulet is, like I said, more than enough for anything, even in Hyper. Well, anything except maybe VESPERIA. That festival is evil. Are you on your second loop or higher? If so, you should have better gear. If not, what difficulty are you playing on? Certainly not Hyper on your first. If you are, just put that record aside. If you don't have good outfits and accessories, you'll never beat Hyper.
Waiting on the other mk2 avatars.Patiently.
