Each strip is that field’s whole ranked pool, with the notch where Vel Tech Rangarajan Dr. Sagunthala R&D Institute of Science and Technology sits in it, in the colour of the band that rank falls in. The track under the rate is the rate itself: it carries no world mark, because the world rate differs by field (from about 6% to 21% in this record).
