Each strip is that field’s whole ranked pool, with the notch where Hamamatsu University School of Medicine 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).
