Different versions of the sprint results were published, because the fully automatic electronic timing system was malfunctioning. The first version displayed below on the left hand side was officially used to determine the athletes qualifying for the finals (best times, q). Later, there was a second version (not displayed). In December 1988, British statistician Richard Hymans published a revised version for the IAAF and the ATFS where many times were corrected. These numbers are displayed below in parentheses. Finally, there were a couple of hand timing results (Heat 1, 110m hurdles men, Heat 1 and 2 200m women; also displayed below in parentheses), because the officials noticed a defect in the electronic timing system during the event.[1]
