Not only was the record set without a favourable wind (+0.0 m/s), but he also visibly slowed down to celebrate before he finished and his shoelace was untied. Bolt's coach reported that, based upon the speed of Bolt's opening 60 m, he could have finished with a time of 9.52 s. After scientific analysis of Bolt's run by the Institute of Theoretical Astrophysics at the University of Oslo, Hans Eriksen and his colleagues also predicted a sub 9.60 s time. Considering factors such as Bolt's position, acceleration and velocity in comparison with second-place-finisher Thompson, the team estimated that Bolt could have finished in 9.55±0.04 s had he not slowed to celebrate before the finishing line. Bolt stated that setting a world record was not a priority for him, and that his goal was just to win the gold medal, Jamaica's first of the 2008 Games. Olympic medallist Kriss Akabusi construed Bolt's chest slapping before the finish line as showboating, noting that the actions cost Bolt an even faster record time. IOC president Jacques Rogge also condemned the Jamaican's actions as disrespectful. Bolt denied that this was the purpose of his celebration by saying, "I wasn't bragging. When I saw I wasn't covered, I was just happy". Lamine Diack, president of the IAAF, supported Bolt and said that his celebration was appropriate given the circumstances of his victory. Jamaican government minister Edmund Bartlett also defended Bolt's actions, stating, "We have to see it in the glory of their moment and give it to them. We have to allow the personality of youth to express itself". Bolt then focused on attaining a gold medal in the 200 m event, aiming to emulate Carl Lewis' double win in the 1984 Los Angeles Olympics. Michael Johnson felt that Bolt would easily win gold but believed that his own world record of 19.32 s set at the 1996 Summer Olympics in Atlanta would remain intact at the Olympics. Bolt eased through the first and second rounds of the 200 m, jogging towards the end of his run both times. He won his semi-final and progressed to the final as the favourite to win. Retired Jamaican sprinter Don Quarrie praised Bolt, saying he was confident that Johnson's record could be beaten. The following day, at the final, he won Jamaica's fourth gold of the Games, setting a new world and Olympic record of 19.30 s.
