Speed of sound = 340.29 m / s (dry air, asl)Netero's relative speed when using 100TGB = 10,000 punches/second.Approximate distance a single fist travels/punch= 1 ft.Total distance covered by 10,000 punches in meter: 3048mNetero's relative max speed when activating 100TGB: 3048 m/s, about 9x the speed of sound. Like I said every attack or motion made by Netero's fists is only relatively slower than the Guanyin's attacks. There should be no reason why the Guanyin's attacks should be slower as proven by Meruem not even seeing where they're coming while he could still perceive which of Netero's movements were faster than his.
