the possibility that i didn't mention is that most assume that webb's potential that year was only about mid-3'46, because he ran 3'46.9
however, that was because he ran a race targeting 3'47.6 & therefore the pacing had to be commensurate with splits to offer him a shot of running this ( & likely not overly ambitious as his pb was 3'48.9 from 2y back )
we don't really know how fast webb couda gone that day if he'd had same good pacing but quicker at all the split points ( chasing much faster than 3'47.6 )
obviously he woud fall off chasing 3'44 splits, but who knows about 3'45 ???!!!
now, i'm pretty sure his 800 was close to his limit ( there even seems to be a hint of shock in his face as they approach the bell at that speed ) - a little slower 1st lap & better 2nd lap & i'm sure 1'43.5 was possible
as for 10k, i'm slightly surprised about theoretical 28'24 coming off 27'34 1y before
perhaps ~ ?28'00 is more likely drift down for a 1500 guy backing off the endurance & focusing on 1500/800
so
1'43.5 / 28'00 ->2'12.8 , 3'28.5 , 3'45.5 , 7'28.8 , 13'07.0
the suggestion is that in '07, webb couda gone out at substantially faster than ~ 3'47 pace & not been killed off for solo last lap - maybe even all the way down to mid-3'45.5...
