För en vecka sedan uppdaterade WFDF rekordreglerna för bl.a. upsi: "For upside-down distance attempts, the disc must be released either vertically or with the top surface (crown) of the disc facing the ground. The disc must also travel the entire flight, including the landing, without ever having the underside of the disc facing down. Thus, twisting or “corkscrew” flights are not allowed."
