If you roll just a bit farther (and you must do it carefully) you can do what is called a deep-stage. Deep staging is when you roll far enough into the starting line that the pre-stage lights go out. This will actually raise your e.t. (make you slower), but will help your reaction time. For test-and-tune nights, it's nothing to concern yourself with, but if you get into competition it's something to consider, as many races are won by reaction time.
