no
you can't seem to read or think
the weather cost bannister more towards 1.5s/lap rather than 1.5%
it was cold & windy before run & roger only ran when wind eased off somewhat but it was still cold
spikes have little to do with it, as there was little change in them between '50s/'60s
He does not say that all dirt tracks are 1.5 secs per lap slower
again
learn to think
the weather was main concern for roger
As most with any common sense can plainly recognise, there is a great range in the quality of the dirt tracks
eh ???
what are you rabbiting on about ???
did they use significantly different dirt in different countries ???
for 1st race on dry, well raked or swept dirt track, the underfoot conditions shouda been the same anywhere
and there would be a different return depending on the weather
you learnt something
cold was much more important than track
When asked a direct question in 1984 when still competing and when he was used to racing and training on cinder tracks, he said that a well kept dirt track would be about 0.5 secs per lap slower over a mile
in vid he says 0.5 - 3s
coe is highly qualified to talk about effects on the 800 as fastest 800 on dirt, but he has nothing on dirt over 1500 or a mile
he ran a 3'43 in '76
he has a 3'54.6 mile in '84 but that may have been synthetic track - a race won by 10s, so he was running it hard & he was good for 3'30 that year
coe's 1500/mile on dirt is no record worth considering
He was then asked about the Iffley Road track, and he said that on a day like this (i.e. Wet, cold, windy in Spring) it would be more than a second
rubbish
he says a wet track is more like 2 - 3s/lap
So it depends on the state of track and weather
cold v warm is most important as runs on wet tracks gives unimagineable handicap
As for the 1.5% loss in time for a mile, the lecturer didn't go into much detail and didn't clarify what the constants or variables in the research were
he says "consensus" which means more than 1 asked
that is best statement on the matter made by anyone
the constraints/variables are obvious to anyone with a clue :
it can only only mean perfectly, dry pristine tracks for 1st race of meet
the weather has to be assumed temperate
The fact he was relating Bannister's performance to today's record is misleading
nonsense
a 3'56+ for the track & easily another 1s for the cold
roger wouda been looking at a 3'55+ if running today on synthetic in warm weather
As I've said before, a well kept dirt track that held international meets in a warm climate in the late 60's is going to be faster than a small college track in 1954 England
utter nonsense
dirt is the same everywhere in the world
for 1st race of meet either in US or england, as long as weather is comparable, the times shoud be the same
the only difference is the weather & often in US the weather was far to hot for middle/distance races
just as the modern mondo tracks of the last decade are going to be faster than the first generation synthetic tracks of the late 70's
again nonsense
how many times have you been told that iaaf have mandated energy return = speed of tracks for more than 25y+ & probably back to start of synthetic tracks in late '60s
the energy return is limited to 35%
anyone making a claim that they have "fastest" track is talking nonsense
iaaf have set limit for decades how fast a track can be
So when he uses Bannister as a comparison to today's athletes and quotes 1.5%, that will not be the same figure for a comparison of top dirt tracks of the late 60's and the old synthetic ones.
nonsense
there is no "top" dirt track
for 1st race on a dry track with temperate weather it woud be ~ 1.5% anywhere in world as epstein said
the 1.5s came because it was cold on his day in '54
1.5% is the worst case scenario and relates to difference between 1954 and 2014 tracks
nonsense
iaaf have had speed rules for decades which you can't seem to get into your numbskull
there is no speed difference between '70s tracks & today
