Josuke estimates that Crazy Diamond attacks exceed 300 km / h ... but that does not make sense because:

Crazy Diamond fought with Star Platinum

Star Platinum fights Silver Chariott

Silver Chariott hit the Hangman, which is literally light !!

That's why Crazy Diamond is at least as fast as light
