I'm not really trapped because I know how fast it should be moving to be around sound speed. If a single second passed, and it only moved a dozen feet; that means it's less than the speed of sound which can move 1.1 feet per millisecond. Anything less than the speed of sound in the Narutoverse in my opinion, is slow. Even Kakashi can react to Lightning for example. In order for it to be as fast as sound or faster, it has to be able to hit the target before a single second can pass. The reason being is they aren't even over a hundred feet apart. Even if they were over 500 feet apart, that would make the sword half the speed of sound. Sound can move up to 1100 feet each second. Itachi's sword can only move up to a couple dozen feet each second. Therefore, it is slow too me.

Further evidence is that Orochimaru is able to speak before the blade struck him. Therefore the sound from his lips was faster than the sword.
