If the result of a feat calculation is completely incongruous with the feat itself, it's meaningless (LES)

"Erm well according to my calculations because this character moved these clouds with an attack that the artist just thought would look cool they are actually an island buster you see."

"Erm actually if you look at the latent heat of fusion for water here this character would need to be a city-buster at the minimum here because they made a big ice statue one time"

"Erm well this character punched a mech into a wall and it made a small earthquake so according to the Richter scale and a bunch of other complicated physics equations that makes them a small country buster"

"No the fact that there's a 0% chance the author was thinking about any of this shit is completely irreleveant sorry."

There is absolutely no reason to take any of these kinds of feats seriously when the character doesn't come remotely close to destroying what the battleboarder says they should be able to destroy, or destroying anything at all. Like fuck it, if the characters dodge lasers are you going to scale them to star-level because of the amount of energy lightspeed movement would realistically take? Like at this point you're not even making characters fight one another, you're just creating your own fanfiction version of the character because you're under the delusion that your average shonen mangaka is doing complicated physics equations every time a character uses their physically-impossible powers from the outset. It's even more laughable when the totally legit city/country/planet buster inevitably struggles with handcuffs or an electrified fence or some shit and you have to wonder if the debater has actually read/watched the medium at all or just selectively turns their brain off for any parts which obviously contradict their retarded wank. Fuck.
