you clearly have no clue about dirt tracks nor relative effort expended
yes, hicham was under-performing at bell as he only clocked 2'32.8 = 3'28.3 pace & put in a huge 53.2 finish
you have to offer him
~ 3'25.5/3'25.6
that day at even pace
however, ryun's last 1200 of 2'46.6 was not only on dirt & murderous 95F heat, he was far from all-out thruout that last 1200
he "walked" the 1st 300 in a pathetic 46.5 ( = 62/lap ) just trying to track kip
this really can't have taken anything out of him, probably handicapped him as he deliberately slowed down to track kip
the vid even shows him slowing down at the start to get with kip
when keino made his move at ~ 300m in, ryun speeded up to ~ 60.9 at 400
( bailey 60.9s at 440y with ryun ~ 3 - 4m back -> 60.9 for 400m, which tallies with t&f timing crew )
he therefore only went about 60.9 at 400, meaning 57.5+s pace
he therefore speeded up somewhat in that 100 but not flat-out
this 100 wasn't flat-out
kip went 56.0 for next lap which was fast ( fastest ever 'til then ) then slowed to 58.0 to 3/4 mile, probably wanting to see what ryun had left
the 1/2 - 3/4 was nowhere near flat out
ryun blasted 3/4 - 1500 in 38.1 = 39.0 at virtually even pace
( listed as running next 210y in 24.6 - the variations in hand-timing & finding metric marks offer lotta error in less-observed points )
he was in likelihood slowing fractionally last 100 but not by much
( given 95F & worst smog in western hemisphere )
but he has been pretty adamant he couda gone on at near same pace for another 109.344m at similar pace if it had been a mile race
bottom line is, that day, his last 1200 of 2'46.6 =
3'28.25 pace
off a "walk" for 300m & even wasting energy to actually slow down to track kip & then running last 1200 very unevenly at
57.5+ pace -> 300 - 400
55+ pace -> 400 - 800
57.5+ pace -> 800 - 1200
52s pace -> 1200 - 1500
with only the 2nd & 4th phases run real hard, throwing away lotta time in 1st & 3rd phases, i woud offer him that
3'28.25 if flat-out from gun-to tape
that on dirt at 1s/lap to '70s synthetic + debilitating 95F compared to ~ 70F expected for a 1500wr attempt + worst smog in 1st world city
