The position of the start gate determines the takeoff speed, or "inrun speed", creating a difference of as much as depending on whether the gate is set higher (thereby lengthening the inrun) or lower (shortening the inrun); the difference in height between individual gates is . Based on the jury's decision, the gate position – of which there are several available numbers – is subject to being adjusted accordingly, including between each jump. In especially tricky conditions, athletes may sometimes be forced to exit and re-enter the gate multiple times before they are cleared to jump. The practice of gates being adjusted too often has become highly unpopular for athletes and audiences.
