....what do you mean. Count the points. On your fingers. Under the person's name that's being judged just like any other sport that points are counted and wrote down or typed? Whether you stand up and look at the cars or look at them with a camera doesn't matter whatever suits you. Drifting is judged the same some more technical on Angle Entry speed Entry Proximity Initiation How close you're chasing compared to how close your opponent is than you know your chase or lead run Clipping points. Etc Hitting zones Is your question you are asking literal? Because it sounds like from what you are asking is how does anyone know or remember who or where and how they allocate points to a certain individual. Or are you asking how and what they judge to determine who takes the round. You can use your eyes and pencil and paper. Or they can replay with camera footage to slow down get technical when it's close
