I think all of these require an improvement of 0.5-1 second per lap on current WRs to achieve. I think it's much more likely that someone can fluke that 1 second for a single lap in the 800m than someone can do it for 20+ laps in the 10k. I certainly think Cheptegei can take the 5k record but not under 12.30
This is oversimplified thinking. “Well, 1 second is less than 20 so I’m going with that.” Wouldn’t you think that the shorter the distance the closer we’ve come to human potential, and the longer the event the more room there is to smooth out the variables and “perfect” a record run?
In the marathon, the WR was lowered from 2:05:38 to 2:01:39 from ‘02 to ‘18. In terms of percentages, that’s like the 800 WR being lowered by 4.53” (or like 1:41.11 to 1:36.58) over the same period. Instead, the record has been lowered by only .82” in the last 39 years.
There aren’t really any “flukes” in running, either you’re physiologically capable or you’re not.
