Ok, you are saying that Ches has the potential to run 13:0X in his career. For sure. True, Mead, Derrick, Jenkins, Hill... have run 13:0X. Why not Ches. He may do it one day or he may not.
However, Knight also has the potential to go 13:0x in his career (perhaps even 12:5x). Knight ran 13:17, which was great race for him. In a few years, he may be disappointed with a 13:17
We can't say right now that 13:24 is not a good race for Ches. Had Knight not been in that race, Ches would not only have run his fastest 5000m since 2014, but he would have also beaten the top collegian in that race by 10 seconds.
