Each strip is that field's whole ranked pool, with the notch where SK Group (South Korea) 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 average mark, because the average differs by field (from about 6% in Dentistry to 21% in Economics).
