I believe speed in figure skating should be evaluated by m/s/strokes, not by m/s. i.e. skaters should gain speed with effortless quality, and maintain it in and out of elements. In such terms, Ota Yukina was truly excellent, and could match today's fastest skaters.
Suguri had decent speed, but no match in terms of effortless qualities, compared to likes of Kostner, Kim, Lepiesto, and Ota. Arakawa was considerably better than Suguri, but didn't belong in top notch IMO.
