The supersonic waves described are just sound waves he is emitting and combining with wind. I doubt that they have anything to do with the actual speed of the gust itself.
What do you think Supersonic is. Supersonic is the speed of the gust. There nothing disproving other wise. Supersonic is a speed.
The term supersonic is used to define a speed that is over the speed of sound (Mach 1). At a typical temperature like 21 °C (70 °F), the threshold value required for an object to be traveling at a supersonic speed is approximately 344 m/s, (1,129 ft/s, 761 mph or 1,238 km/h). Speeds greater than 5 times the speed of sound are often referred to as hypersonic. Speeds where only some parts of the air around an object (such as the ends of rotor blades) reach supersonic speeds are labeled transonic (typically somewhere between Mach 0.8 and Mach 1.2).
It wouldn't have been considered a speed feat by the sound nin that were in awe by it if the attack wasn't fast. There is nothing disproving that the waves arent supersonic. You even said it your self. He emitted the waves. The Same supersonic waves Sasuke dodge while carring Naruto and Sakura w/ shunshin.
hell in the itachi fight w/o shunshin he moved faster than his shuriken can travel. Everytime Shunshin has been shown it has shown to be near instant movement in almost the sense that its basically teleporation. Evidence and descriptions and translations all around support the claim. I dont see why its that hard to beleive
Shunshin no Jutsu is a basic Ninjutsu technique. The ninja will appear and disappear in an instant, allowing them to retreat or attack suddenly. To facilitate the movement the ninja will often use nearby elements such as mist, sand or leaves to mask their appearance or disappearance.
The fact that Sasuke speed with it has been praised by even Akatsuki members. Says that Sasuke is extremely fast with it. It even caught Itachi off guard and he has sharingan to track high speed and predictmovements. So soo much evidence prove that is past Supersonic closing in on Hypersonic. Hell not to try to use anime but in the anime when Sasuke uses it a small sonic boom can be heard when he uses it.
