I called the 45.9 but the wrong winner. I called the 21.5 with Thompson and I'm calling a 51.3 for Sydney in the 400H and it is 2:23pm PST. Its not the MONDO track its the heat and humidity. Blood cells boil in the heat and night races are much faster. The fast track is the German model Regupol. There were (6) 9.8's or less in two semi's in the 100. The final Bolt went 9.58, Gay 9.71, Powell 9.84, Bailey 9.93 Thompson 9.93, Chambers 10.00
