I am currently 12 seconds from rank A. However, if I look at the individual races and add the distances to the first-ranked racers in B - which must be about the same as the last-ranked racers in rank A - it amounts to only about 2.5 seconds. So where do the additional 10 seconds come from? What am I missing?
