Today’s post comes from a co-worker and looks at the increase of speed in speed skating in the Winter Olympics since 1924. It does a nice job of showing the increase in the speed. Because to a degree, the increase has not been linear. Instead, it really only increased in two spurts and recently has remained fairly constant.
Then to show how slight differences in speed impact an actual race. The times are plotted against the distance in a simulated race. That shows that seemingly incremental increases in speed can have a drastic impact on where one finishes a race.

Would have loved to have seen the WSJ incorporate technology introductions into the project. The clapskate comes to mind, aerodynamic clothing too.
