because as college kid he woud only likely run 400 on a relay
you think this looks embellished ???
http://kuhistory.com/articles/ryuns-run/On April 23 of that year, with his 19th birthday less than a week away and storm clouds gathered overhead, Ryun took to the rain-soaked track at Memorial Stadium and shattered the 12-year old Kansas Relays mile record by more than seven seconds. The KU prodigy admitted that the wild cheering of the unexpectedly large crowd “spurred him on” to the fifth fastest mile in American history. His time of 3:55.8 represented the best time anyone in the world had yet recorded that year.Later that day he anchored the freshman mile relay team for KU and despite receiving the baton 20 yards behind the leaders reeled them in with a 46.9-second quarter-mile to give his team the victory
That link reads like the opening to a novel. A lot of embellishment.
There is no way of measuring in hindsight how wet the track was and no way of calculating what difference it would make to the time. Yet you generously offer 0.9.
You say initially he ran a 46 leg, which you then give as 46.9. In T&FN at the time and in reference books I have, that leg was given as 47.0.
It would have been hand-timed, which gives a faster time than electrical by 0.2. Without any video archive there is no way of ascertaining how accurate the time keeper was. It could have been an electric time of 47.2 or even slower.
It was a relay so he had a rolling start. For this you need to add 0.5 -0.7.
Split the difference and you get 47.8.
Take off 0.3 for it being 440 and it gives 47.5 for 400m.
You then give 1.0 conversion from dirt to synthetic. Again, no scientific evidence supports this. Certainly the world's top 400m runners in the 60's didn't all improve their pbs by 1.0 sec when moving away from dirt to synthetic tracks. 800 guys din't improve their pbs by 2.0, Milers by 4, etc.
So no evidence that its worth a second faster.
Even being v. generous, it's worth 46.5 max. And this was the same season he ran his fastest 800m, on synthetic, in 1:44.3. Again, hand timed and more likely 1:44.5 electronic. There are many athletes who run their fastest 400s as teens (Ovett) and it doesn't follow that as your 1500 pb improves, so does your 400m. There is nothing to go on as evidence that he was able to run faster over 400 or 800 in 67 compared to 66, except your dreams.
And it was a week before he turned 19, not 17 as you previously alluded to.
Only a fantasist like yourself can make a 46.5 into a "45 low"
If Ryun felt he was in 45 low and 1:40 shape in 67 then he'd have had a good go at it. He didn't.
I'd give a peak Ryun in 67 around 1:43.0 on a synthetic track.
