As 18'er said, there are built-in rest times in the CFA. By the time everyone gets to the run at the end, they are somewhat tired, and their run times may not be as fast as they would be if they just did the run and nothing else. That is part of the test. Super scoring would defeat that purpose. You have passed the CFA with flying colors, Rufus. If you retake, you may not do as well on some other section.
