Ok I am finally back (also please do not spam "I disagree because these arguments are old", at least debunk these yourself ffs):
Problem 1: Anti-Statements
It makes absolutely zero sense for Polnareff (Silver Chariot) to be Massively FTL when he himself literally concedes inferiority to Hanged Man in the first place in both combat and reaction speed (again, for Chariot, not his normal form). This matters because Polnareff is literally the one controlling Silver Chariot in the first place which we know is the case because that's how Close Range Stands work in the first place, it isn't an autonomous or posthumous stand like Sheer Heart Attack or Anubis for example. So if Silver Chariot is MFTL, so is Polnareff in reaction and combat speed. Which is wrong according to the man himself.
There was also a moment where Silver Chariot was capable of intercepting Hanged Man from a further distance away, but not only did Polnareff himself get blitzed, that interception was only possible because he knew of it's trajectory. In other words, Silver Chariot needs to aim dodge the light. Even Centerfold, the user of Hanged Man, acknowledges that Polnareff has to aim dodge the attacks and when he becomes unpredictable, Silver Chariot literally cannot do sh*t against him. If Silver Chariot was MFTL, the unpredictability of a SOL attack wouldn't matter here.
In fact, that's literally the whole point of Polnareff defeating Centerfold in the first place, he had to force Hanged Man to move a direction that Polnareff knew he would be going so he could tag him; if Silver Chariot was MFTL, then there would be zero stakes in that fight whatsoever.
To be clear; I am aware that Stands and users aren't accepted to be 1:1 in speed, but Polnareff (and thus I) would be talking about Silver Chariot itself + Polnareff's own reaction has to scale to Silver Chariot for him to control it in the first place
Two issues:
1:
Polnareff himself isn't listed as even having MFTL reactions on his profile. It's important as other characters like
Jotaro and
Giorno have MFTL reactions off them having feats of physically reacting to other stands' movements. Polnareff doesn't have these feats.
2: Polnareff cannot see through Silver Chariot.
It's a key point of the fight against Ebony Devil (posting the anime too for reference):
If you have a super fast blind robot that you can command, it does not matter how fast said robot is if you can't see the target, much less one that is so small that it's smaller than a human iris.
Even then the thing fails to take in account that Silver Chariot had to literally get away from the civilians in order to not harm them, given that Hanged Man was literally hiding in their eyes due to its ability to exist only in reflections of shiny surfaces:
Problem 2: Anti-Feats
Silver Chariot being MFTL also makes the scenario where he fights the Sun pretty much an illogical fight because that Stand, which is accepted to have lightspeed attacks because of the numerous statements of it using light in general, makes SC struggle to even react, even when the former Stand was firing from a distance further than 100 metres away. Someone with MFTL reactions would easily outpace the Sun's beams here with short movements yet the Sun is clearly going relative to his reaction speed.
Ignoring the Part 7 bit as I am not knowledgeable there... I don't see how is that an anti feat? Where is Polnareff struggling here? All he's doing is deflecting these beams.
Plus, did you forget these Stands are literally
short ranged? They cannot go away for more than 2 meters away from the user unless you're Hierophant Green, having ghosts that can punch at MFTL is useless if you cannot use them to move away at such speed.
Problem 4: Calculation Assumptions
The calculation itself pretty much assumes that Silver Chariot did all of that distance when the light moved a miniscule one, which is a very extraordinary assumption. While yes, in the anime those distances were what was happening in the feat, that's not necessarily what happened in the manga because all we see is Silver Chariot react to Kakyoin scream "NOW" and then we see SC appear; there is nothing that speaks against the conservative interpretation that Silver Chariot moved as the light started to move in the manga or even before that. Unless Kakyoin screams "now" at speeds massively faster than light of course
Furthermore, the anime version of the scene blatantly contradicts established statements and feats in the manga itself, which I established in the other sections above.
I do not agree with using the anime version (why was it even used to begin with), the idea of Silver Chariot flying towards the coin and then slashing HM when it's mere centimeters away from said coin is consistently shown in both the 2001 and 2015 adaptations:
Araki is indeed involved in the anime,
he aids in writing anime-only scenes too, so I do not think that the anime is capping with the idea of Chariot slicing HM when the latter is really really close to the coin lol. Again, I am not ok with using the anime version over the manga, but it clearly gives an idea on the intent of the feat.
Problem 5: Outlier
Even without all of the problems in general, the feat is not even close to being consistent in the first place because this is the only feat in the verse that gets this high in speed. The only other feat in the verse that's even close would be Kars' blocking Ultraviolet light (which is around 5.6x slower than SC's feat), which not only is wrong because not only is that not how ang sizing works, the feat blatantly contradicts the point blank feat standards that we have on here which say this:
And if Kars was actually 40 times the speed of light, he wouldn't even get tagged or hurt by the UV light in the first place, bro woulda outpaced it super easily.
I am also aware that Kars was off-guarded by Stroheim here, but that doesn't handwave the fact that a 40x disparity in speed wouldn't allow an off-guard to even happen in the first place unless explicitly stated.
You're very conveniently cutting out this part:
This should only be used when the character in question is greatly superior to the one who's attack he is evading and the speed of the attack is concretely stated, such as being able to surpass the speed of sound, or light, or uses a basis in the Real World such as the speed of an athlete's punch.
Stroheim himself isn't even MFTL in Combat Speed, and in fact,
Kars literally clowned on him the whole fight otherwise, Stroheim only managed to catch him off-guard there.
In fact, this gap was shown even in the anime even better:
Kars also has the plane anti-feat, but it's not that important to adress as that's pretty much just PIS, honestly.
Same Kars who could move so fast that he disappeared and made a fake of himself before his own light has dissipated, btw.
Anime also shows this.
