What we seem to be forgetting is the impact of 90' temps on athletes mental and physical comfort. That may have been a 12:4X effort/expenditure. Every athlete in the race knew any erratic or poor use of energy before 4k was likely doom. I agree with most that over the last 800m someone should have made Jacob more uncomfortable. In the moment athletes to make hard choices and don't want to sacrifice silver or bronze still believing in their kick for gold.
