a +3m/s wind on one straight with a -3m/s on the other is about
0.30s
disadvantage compared to 0 wind thruout
therefore, 2 sets of these offer
~0.60s disadvantage for 2 laps
depending upon the direction for remaining assymetrical 100m,
disadvantages by a further 0.40s
or
advantages by 0.25s
using 3m/s as a posit,
cram was scuppered by either
1.00s or 0.35s
his splits woud indicate former...
Talking bollocks again! One set of formula does not apply to all in Venty land.
Remember when you posted this on here back in July?-

no
it affects times, but not by the nonsensical amounts posters believe
a 10.14 flat guy with +3m/s runs ~ 10.00
same guy with -3m/s runs 10.35
( from wind/altitude calculator
http://myweb.lmu.edu/jmureika/track/wind/index.html)
basic = 20.28
windy = 10.00 + 10.35 = 20.35
a difference of 0.07s on straights for 1 lap ( you can redo these with a 800m guy of 1'41 with average 100s of 12.6s instead, but ratio will still be virtually the same - we are talking barely a tenth of a sec ultimately )
on curves, wind has somewhat balancing effects, but obviously still detrimental - give it another 0.05s overall for both curves in a lap ( it cannot be more than the wind effect in the straights )
therefore, a 3m/s wind gives a ~ 0.15s handicap/lap or 0.3s over 800m for 3m/s constant wind in the stadium
try again
1000m is 2.5 laps, so according to your former calculations that's 0.15 x 2.5= 0.375.
Now you come up with 1.00. No mention of drafting either. You're always contradicting yourself.
All of which is academic anyway, for as other posters have said, the wind level was exaggerated or dropped. There was no reading of the wind speed during this race so your calculations are pretty meaningless as usual.
