What do you think Kiplimo would gain to make it a 12:40-12:50 race?
In my opinion Kiplimo is best when he sits in the field until say 800m out and then makes the long run for home. Unfortunately for him another guy (with a similar surname) can do the same.
I don´t think the 2 last 5000m finals were 400m races.
In Eugene a Norwegian runner took the lead 900m out and squeezed the pace before he ran away in the last bend.
In Budapest the Ethiopians set a high pace from 2000m out so these historical fast times were run:
last 2000m 4:56.69,
last 1600m 3:54.14,
last 1000m 2:21.07,
last 800m 1:50.65
last 400m 52:45
last 300m 39.09
last 200m 26:20
Last 100m 12.45
But unfortunately for the Ethiopians the same Norwegian ran away from them again this time over the last 300m beating a Spaniard of Moroccan heritage on the last meters for the gold.
