800m conversion standard 1 believe is just the 800m/880y conversion of 0.994
his 400 ability in '67 is pretty much unknown but my instinctive reaction has always been that with his legendary kick it musta been about 46.0 on a synthetic track ( i've thought that for a long time since watching his vids )
i never thought about "testing" his hypothetical numbers before i've just tried some numbers on here :
for '67 i tried 46.0 & as i have proferred in the past, i reckon his 3'33.1 was worth 3'24.5 - 3'25.0 under perfect settings
so :
46.0 with
3'25.00 ->1'41.09
3'24.75 ->1'41.02
3'24.50 ->1'40.95
it gives virtually same estimate as above for his 800 ability in '67 - that's from a computer programme which doesn't care what your name is or what your opinion of an athlete may be - just cold hard indifferent electrons
you may or may not believe me, but i've just done this building on your request ( i thank you for giving me the idea ! ) & it tallies well with empirical consideration of his 3'33.1 & suggested 800 ability in '67
so, 2 different methods give similar conclusions - one empirical & one a computer analysis
sometimes, people have to set aside their personal beliefs & prejudices & do some cold hard analysis & then have an open mind to the conclusions
