There is a decent article on the guardian website about why the margin for var offsides needs to be 20cm. Basically some maths professor has said what people on here said after the spurs game. Ie the frame speed used means that a player can move 15cm between frames, which means presumably if players are moving in the opposite direction the this will double. The line drawn also has a margin of error assuming the goal line isn't drawn using a laser. In addition the moment the ball leaves the foot is impossible to pinpoint as the ball becomes concave when it is kicked. In short, like any measuring system it has a margin of error. In this case way above what is currently used whereby having a japs eye over the arbitrary line is seen as a clear and obvious error.
