I think Lemaitre should no show for the semis.
As far as I can tell from the results from the heats, he has no chance of advancing.
He should save himself the energy and stress, and just focus on the 200m.
Heat ?
Sure, in the first race, the temperature was 17°c and in the last race 31°c LOL
Your knowledge are better than scientists or IAAF, i'm impressed LOL

"The International Association of Athletics Federations (IAAF) acknowledges the effect of a tailwind by setting strict criteria – a time run in a tailwind greater than 2 ms[SUP]-1[/SUP] cannot count for record purposes. The effects of wind on the time for a 100 m sprint has been discussed in journal papers and at conferences and they generally agree that a tailwind of 2ms[SUP]-1[/SUP] improves a time by about 0.1 s"
