Ninja Of War wrote: I still think it should have shown to visibly increase his speed. The series has always been extremely fast-and-loose with speed. If you derived some ninja speeds and applied them consistently, it wouldn't make much sense anymore.

IE Kojaku is a technique most ninja should be able to perform, and Guy's Night Guy technique would've created a continuous thermonuclear explosion.

So really, it's for the best that the series uses Rule of Cool for most speeds.
