I am a fan of getting times as much as possible and as much as needed. At higher levels getting splits is necessary to see what is working. Time, video, and annotate what is going on in practice just to keep good records of what is working. I am very interested to see what happens this year with mens and women’s sprints and hurdles at London. Look at the world class hurdler at the end and see how easy it is to collect meaningful data.
