How can you possibly tell where they are hitting their top speed?
Not trying to pick on you Zack, but I’m with Callam here. The eye can’t tell when an athlete has stopped accelerating. And lots of 100m guys from the 80s would be fully erect by 20m, and still accelerate through 60m. Ben Johnson was the most notorious, but Carl Lewis, FloJo, and lots of other athletes were in the same boat. I actually favor tall posture quickly, but that’s another topic.
