No, KE rules aren't that restrictive. You are deadass arguing that we shouldn't use any KE calculation, essentially due to existence of contact damage(again purely gameplay mechanic, Frisk wouldn't actually receive any damage if they just touched motionless monsters). Besides, verse not having clear correlation between power and speed is not overall disqualifier of KE
calcs, only disqualifier for certain
type of calcs. Current
calc, and all others KE and LS don't require for verse to have a such clear correlation to be valid. They are valid by current standarts, period.
I don't know why you're still saying that when I already explained it to you a total of
5 TIMES that just because something isn't written out on the page doesn't mean it isn't a disqualifier, a CGM (Joakin) even came here and told you that
it is indeed a disqualifier if said Kinetic Energy is proved to not increase the potency of the attack in-verse, regardless of the size. The page is there to give you an idea of how the main rules work but you still need some logical and criticial thinking when applying kinetic energy to an attack. Going by "but the rules don't say that" is killing common sense.
I will tell you again, read the literally first part of the rule that you are copying from: "
Kinetic Energy based on Movement Speed is case by case", they then say examples on small objects yes but it DOES NOT stop there. They are giving you
examples, and so is the "Speed can be used to find KE when" and "Speed cannot be used to find KE when" sections. They are
EXAMPLES, not
all possibilities. Your "giant" rule in "can be used" is an example where its regularly valid to do it, however it will vary from situation to situation, not ALL giants over 200kg will be valid for KE depending on other factors, here with Mettaton, regardless if you are inflating the values for him to be 6x over his regular size for no reason other than overscaling, it's a completely different situation where KE is just invalid via multiple other factors of logic within our rules and basic common sense.
We recently had CRT about Naruto you linked(should lifting 1 kg sword at relativistic speed give you Moon level LS). Staff decided that verse doesn't have sufficient correlation between speed and power. Does it mean that all KE calcs are invalid now? No. Why? Again, proving correlation between power and speed inverse is needed only for certain type of calcs.
This is not about "proving the correlation". This is about,
alongside all the other issues with the calc that wank it to be even close to valid named on OP, there's a
direct contradiction to that correlation which is a completely different story, if such a thing exists then it is no longer about said "giant or not" it's "KE is literally a non-factor here, why are we using it?".
Esteemed CGMs can decide that current KE rules are too relaxing, and we should be more restrictive towards them, and current KE calcs of the verse should be gutted. It is absolutely normal position. But such things shouldn't be discussed here, but in distinct Staff Discussion, since changing them would change situation for almost any verse in site. This is not place for such a discussion.
This is already something done in the current KE rules because it is quite literally just common sense. And yes the current KE calcs of the verse should be gutted, or at least alot of them should. I point that out IN THE OP by saying Sans's Bones KE and Papyrus's lifting bone strength KE calc should likely also be completely removed by the same reason Mettaton's would aswell. These all make no sense within the verse, this is the definition of overscaling a verse because "why not" and ignore what it's actually being portrayed/showed, which I can tell you, is not KE.
Also even if they are kept, both Dale and Life of King already explained how UES doesn't mean you can apply that lifting strength to their physicals etc.
This is not about consistency at all. Inconsistency is when different panels show same objects at totally different size. This is not our case. We can see Mettaton attack legs and his actual legs at same time, and we can clearly see that his actual legs are much smaller. Are attack legs his actual legs(so they shouldn't be bigger than them) or not(so they can be much bigger than them) is important question. But it's not about unreliable pixelscaling, it's about questions such as "How much battlebox is diegetical", and it's not sphere of expertise of CGM.
Again, they are representations of his legs or magic versions of his legs that he summoned, either example gives the same concluson that saying they are 6x bigger than his legs is a complete strech. A regular CGM can tell you "why are you using density of his regular leg with electronics/devices etc inside it for a magical leg" or "why are you pixel scaling this leg size via the soul when you literally have views of the same type of leg on the otherworld". The whole calc is inflating values via an
inconsistent powerscaling method (battle box) so it's wrong regardless, it's that simple.
Objects are
consistently shown to be a different size in the battle box, this is a matter of completely banning pixel scaling battle box scaling unless there's no other way (Ex: Pyrope's bomb). Not even touching on the fact that
souls themselves have inconsistent sizes throughout the game. This is indeed a consistency issue in the pixel scaling of the verse.
