Owens' WR of 8.13m on May 25, 1935 was reported as aided by a wind of 1.3 m/s. >> My knowledge on the subject is woefully lacking, other than being able to contribute that the IAAF adopted the 2.0 max at the '36 Olympic Congress in Berlin (right before the Games) and that the 2.0 rule was enforced in the subsequent Olympics. The rule was enforced retroactively at least to the point where a 100 mark by Owens at the '36 NCAA was rejected as a record. I can't swear to it, but I'm pretty sure that the AAU was rejecting American Record status for sprint marks basedon strong tailwinds (but I don't know if codified) prior to the IAAF action. gh
