Speed in Sainen is determined in relation to how fast the average person throws a kunai, where x1 kunai speed is that speed. As this speed increases we come closer to the speed of the fastest known thing in the current universe which is that of the bijuudama at x10 kunai speed. However anything instantaneous such as flying thunder god is determined as x0 kunai speed as it is the instantaneous transportation from one location to another, and is 'incapable of being dodged'.
