I don't think that proves the amps are the same, you're relying on superiority for scaling and then using relativity to prove them which idk what you wanna use to say theyre relative
anyways the argument that the ranking exists in a general sense is disproven by the blut rankings, so its clearly not in general, now the remaining other argument to make is that the amps are the same but I'm skeptical to that because volstandig is a superior and more spammable version of letz still, and both of those techniques involved using the environment to amp yourself, we see candice's one pop ou
t unintentionally thanks to the environment, if it is environmental reliant it is going to vary which defeats the point of them being the same amp
and it being something you can learn as stated in the earlier scan+ requiring control so as to not accidentally pop them out means its a skill based technique, makes me lean towards believing it would be like blut as you described earlier
