Ok, I did not know where to post this, so I thought I would ask in the debates. I heard that Ben Johsons once did a wind aided 9.64
True or not. this would be the best place to ask. I know he thought that if were running today he would do 9.55-9.50 thanks - its just a curiosity.
Not true unless it was hand timed.
from memory there was a wind aided (+3.5) 9.7h in canberra (or perth) in '87
