so to me it wasn't really clear I have 2 questions: Does Goku also have the 3x rates on the 2nd step? and about the Ultra Z power is it only for Frieza or do we also get Goku's as well?

Tani says "characters we just introduced" while also only mentioning "Full power frieza" right after

either Tani just mistakenly used the plural form of character or they just didn't show the version of Goku for some reason

doesn't help that before he even says "characters we just introduced" he specifically says "event related to full power frieza" I mean...I get that if it counts for both of them it's not entirely wrong, but this focus on frieza seems a bit suspicious and leads me to believe Goku doesn't get these bonuses for some reason? (I hope I'm wrong and I would be happy to be wrong)

if anyone can clarify what he means that would be really helpful, would help if people can double check what he says in JP to see how he said it in his native language
