Relative Work (RW) is when two or more skydivers build formation by gripping each other or specially made "grippers" on their jumpsuits.
There are two kinds of formations, called randoms and blocks. The randoms are singular formations with full separation of all grips both before and after building the formation. The blocks are double formations with a special designated movement pattern in between, called an inter. The start formation may, or may not be similar to the ending formation. The inters are differently performed.
In competition, the winning team will be the team that has collected most points, by completing the most correct formations within time after the final round is ended. In case of weather or technical problems, or other causes, a competition will be valid as long as all teams has completed at least one round.
