Masaru Head + T-Shirt = (169.1/416) x 229 = 93.0862981 centimeters.
Angle between Elecmon and the Screen = 2atan(tan(70/2)*(185/764)) = 0.228466262 rad
Degrees = 0.228466262 rad * 180°/π = 13.090152573 degrees
Elecmon Size is 93.442623 centimeters.
Distance = 407.22 centimeters.
Angle between Masaru and the Screen = 2atan(tan(70/2)*(387/764)) = 0.471105547 rad
Degrees = 0.471105547 rad * 180°/π = 26.9923595483°
Distance = 193.92 centimeters.
Distance between Masaru and Elecmon = 407.22 centimeters - 193.92 centimeters = 213.3 centimeters
Here you can see a compilation of information about the electricity in Digimon with constant evidence that the attacks act like real electricity and here you can see a calculation that shows that the level of power of the Digimon Child is comparable and superior to that of real Lightning.
Elecmon's lightning has to travel the distance between Elecmon and Masaru while Masaru has only to traverse the distance between him and the PoV.
Timeframe = ΔS/V
Timeframe = 2.133 / 4.4e+5 = 0.00000484772 seconds.
Masaru Speed = 1.9392 meters / 0.00000484772 seconds = 400023.104 m/s, mach 1166.24812.
Masaru Speed = 400023.104 m/s, Massively Hypersonic+.
Consistent with the speed that other Digimon have already demonstrated in the franchise.
