Both results on one pace scale, with no line drawn between them — these are different race formats, so the gap is mostly the race rather than the runner.
1 result is not on this chart. They are counted in every statistic above and listed in full below — backyard ultras carry a lap count instead of a pace, which is the number that means something in that format.
