The final at major championships is all about racing not times. On many occasions faster times are set prior to the championships and during the heats. A good example is Fred Deburghgraeve in Atlanta. In the heats he broke the world record for the 100 *** and many were saying that he would go faster in the final and be the first man under 1 minute. However he went slower in the final but still won gold, albeit just from Jeremy Linn. I agree that Sydney will be generally faster than Atlanta, maybe much faster but we should recognise that at the Olympics it is not about times, it is about medals.
