Introduction[]
In Chapter 56 of My Hero Academia Vigilantes, Knuckleduster scopes out Number 6, before shooting him with a rifle. After figuring out where his assailant is, Number 6 dashes over to the location of Knuckleduster, with KD not being able to react.
Calculations[]
Fortunately, Knuckleduster gave us a distance between him and Number 6, which is 250 meters, but N6 probably travelled a longer distance with all of the hops he made; Knuckleduster's 250-meter figure was a straight line between him and his target, meaning that N6 crossed that distance and then some. Number 6 dashed and presumably got there before Knuckleduster could react, judging by his shocked face once N6 arrives. We'll assume Knuckleduster has Peak Human reactions as a low-end and superhuman reactions as a high-end.
250 / 0.102 = 2451 m/s or Mach 7.15 (Hypersonic).
250 / 0.08 = 3125 m/s or Mach 9.11 (Hypersonic). 9.11, eh? Funny, he did try and blow up a tow-
That isn't all though. As stated by Knuckleduster, in normal situations, Overclock increases the user's speed by three to ten times, with that becoming a few dozen times in emergencies situations, like having a rifle pointed at you or trying to analyze a voice recording playing at over three-hundred times normal speed, both of which happened to Number 6. "12 / 10" is x1.2, so we'll multiply our results by that.
(2451)(1.2) = 2941.2 m/s or Mach 8.57 (Hypersonic)
(3125)(1.2) = 3750 m/s or Mach 10.93 (Hypersonic+).
Hey also, the voice recording was played at three-hundred times normal speed. According to this website, humans can process sound in 0.05 seconds. 0.05 / 300 = 1.67e-4 seconds which is High Hypersonic Reactions. That would only scale to emergency situations Overclock Number 6 since listening to the voice recording was one of the examples Knuckleduster gave for emergencies.
