Each team gets 1 official race run (some events allow 2 runs with best time counted); Pre-race "show" performance at the start line — 30-60 seconds of theatrical content judged separately; Race start: gravity-only descent — pushing permitted at the start, no propulsion during descent
Why people argue about this
People often assume that the initial 3-second push from teammates at the start is just a minor detail, but in reality, it's a crucial element that can give one team an unfair advantage over others, leading to heated debates about its fairness and implementation.
