The currently listed world record for Defection SA is 0:37 shared by Ryan Dwyer and Marcus Dolejsi (Karl Jobst, who has since been banned from the rankings, has 0:35).
They do use strafing, but that isn't as important in Defection as a trick that allows you to fall outside the building then go back in. In Special Agent, you have to use that trick twice, and have to land on a thin wall the second time for optimum effect.
