You guys are jonning about speed again? Being faster is an "extreme".
There is no "I'm almost as fast as /b/", because you are still slower and will stay that way every time.
If Nidoking is faster than Tyranitar by the most miniscule amount you can conceive, then he is still faster than Ty, and will always be faster than Ty.
I think this bit of dialogue is a fine example of my point:
Shinomori Aoshi : "One width of paper closer, and I'd have sliced your jugular."
Kenshin : "But that narrow margin is the key difference between me and you in your present form."
