Its like usain bolt being the fastest runner. That's one thing. It's another thing to be the fastest runner on a path that's not a gentle arc. Fastest runner when a friend just got attacked and you're frantic. Fastest runner being chased by someone as fast as you, that won't hesitate to kill an innocent if you don't keep your head in the game and get caught slippin. Fastest runner when you just woke up 2 seconds ago. Fastest runner when fighting someone that can outsmart you. Fastest runner when your enemy slipped a poison that nerfed you agility. Fastest runner in a foreign domain. Fastest runner when you've been running for an hour. Just cause you clock a certain upper limit for a superpower doesn't mean you'll exert that in every instance...
