To earn badges after collecting them in previous runs, do you have to make a fake account to do another attempt or is there a setting to remove the badge already collected?

Well, having fun using the damage cancel I found this. I don't know if someone has found this yet.

Im doing glitchless jabu jabu and I dont know when to start the time. I've been doing practice runs starting when the screen fades to black after Jabu eats the fish. Am I starting the time wrong?
