Fundamental flaw: This has nothing to do with the CRT
It's considered an extremely difficult technique, so it doesn't need to be said that this is a explicit skill feat.
Flashy is consistently noted as being so superior to other ninjas specifically because of his skill
this was stated by the ninja duo, sonic, and flashy himself on more than one occasion, so this has absolutely no business being mentioned in the first place.
Except this is either just untrue or badly out of context.
relevant scenes include
1. Them not knowing how strong flashy is on their first encounter, when it was literally impossible to know how strong/fast he was when they had no prior knowledge on him, as well as him having held back until they unleashed their sealed monster form speed
2. Them challenging Flashy, with the perception of his power and speed from when they fought in the monster association, to then be defeated,
immediately acknowledging he's superior to them, and then stating that he got stronger, which we have direct confirmation of this being the case.
so by "proving multiple times to have a bad understanding of what Flashy can do" what you really mean is "they didn't know information that was impossible to know, then proceed to lose to an amped flashy do to information that they also didn't know" and what does that prove exactly? Absolutely nothing relevant, because we're not scaling them to current flashy, we're scaling them above their perception of Flashy from the MA arc, whose full power they got a good estimation of in the last phase of the battle, as is being accepted in this CRT already.
Forcing Flashy Flash to use an
ultimate technique, then
reacting to said ultimate technique, then getting shocked at the skill that is consistently stated by literally everyone to be on another level.
That is not how anti feats work.
The "maximum speed" thing is just to indicate that he was going all out from the very beginning
but since he didn't say "maximum speed: flashy fist" when using it against Saitama and Platinum sperm, I guess that means he was suppressed against them too. (he was not)
"Ultimate technique" and "Maximum speed" are interchangeable, that maximum speed thing was used once and never used before that or after, so it means nothing.
In terms of pure raw speed and AP, he is comparable, but slightly inferior to Flashy
Flashy has skill on another tier, which is why he was much more dominant in the last 2 fights, but that is it.
And just to get an idea of how much this skill thing is hammered in.
no.
