Basically i'm going to calc his feat during the Chapter 78 .
Note: The pixel scaling was done on a previous Calc done by God Movement on the NarutoForums.
Calculation[]
I'm going to calculate the speed in which his arm moved at that moment.
Melodias heigh is 1.52m (5' Feet) .
58.2px = 1.52m (Height)
90.2px = 2.36m (Distance of the lightning to him)
24.1px = 0.63m (Length of his blade)
33.6px = 0.63m
28.3px = 0.53m (Length of arm)
I'm going to use the formula for angular displacement. Abouth the degrees... Well, it isn't exactly a 180 degree arm movement, so i'm supposing is 160 degrees... kinda.
s = r*theta
s = 0.53*2.7925268 = 1.48m
Our Speed of lightning = 440,000m/s
2.36 /440000 = 0.000005363636 seconds
1.48 / 0.000005363636 = 275932.222m/s or Mach 804.46
So, Massively Hypersonic
Much better than his older calc with Mach 200+
