I just did a rough calc for this feat:
Naoya is punching at Maki. Each punch is happening in 1/24th of a second, and the entire move is moving from fully extending his arm to punch to bringing it back to his right shoulder, kinda like this
So somoene's wing span = their height, roughly.
Arm length and shoulder to shoulder length are all roughly 1/3 of wing span, so 1/3 of height roughly.
Naoya is about as tall as Choso, so 1.74 m height.
Assuming this is what he's doing, Naoya is roughly moving the green line here in 1/24th of a second, as that is what projection sorcery does:
So he's roughly moving his fist through 2/3 of his height. Sice it's an arc motion, **** it, lets highball it to 4/5ths of his height. That distance is crossed in
exactly 1/24th of a second, so the math is:
Speed = (4/5 {percentage of his height each punch hypothetically moved} * 1.74 m) / (1/24) =
33.408 m/s
So being generous, eyeballing, we get Naoya's attack speed vs Maki here at 33.408 m/s, and this can't even be debated because we know that the timeframe is exactly 1/24th of a second.
TLDR: Naoya Zen'in saw it OK to attack Maki, who he already knew wiped out the rest of the Hei filled with capable semi-grade 1 to grade 1 sorcerers with generously Superhuman+ speeds.
That is just absurd, and consistent with other things in the series, like those Hanami retrosonic bud calcs. Also I'm not saying this should be everyone, but like your average grade 1 shouldn't break past 200 m/s considering this. It's my explanation
@Duedate8898.
Also the idea would be that anytime anyone reacts to a supersonic attack, the thing is moving predictably in a straight line, and the preson who dodges or reacts to said supersonic attack is doing so from a distance, and temporarily uses reinforcement to amp their movement speed to be capable of dodging said object, while normally having attack speed and reactions far inferior, staying consistent with this terrible attack speed being relevant to grade 1s.
Like Kenjaku's feats of reacting to PB, they're from about 10 meters way. So the reaction time to react to that is around 343 / 10 or about 34 m/s reaction times, but that's still enough to temporarily amp oneself to near transonic movement speed in time to dodge, while just having those 34 m/s reaction and combat speeds. I concede this is very like
theory-esque territory, and you could say the superhuman speeds shit is just outliers or something, but I'd say it's an OK personal offsite interpretation. As for the other feats, like Maki reacting to rubber bullets, the rubber bullets could be as slow as you want, and Gege said the feats were exaggerated anyways so we probably shouldn't drwa the most conclusions from this stuff.
Also stuff like Maki tagging mach 3 fits into this because once she knew the mach 3 speeds were coming at a straight line, super predictably, she could unleash an unusually fast punch since she knew the mach 3 speeds were coming and where they were coming, as to not say it's inconsistent panneling which is valid too.
