It is suggested that the Contest Director carefully consider constraints imposed by the time and weather when deciding on the number of flights that is to be allowed each contestant in an event, since in many events a contestant who cannot make both flights will be at a severe disadvantage. In such cases, it is preferable to limit contestants to one flight in one or more events than to impose a hardship on contestants who could not make both flights due to lack of time or inclement weather. If such a limitation is necessary, it should be announced prior to any official flight by any contestant in the event being so limited. In circumstances where it is necessary to enact such a limitation after official flights have been made in an event, i.e., a sudden weather change, all contestants, regardless of how many official flights they have already made shall be bound by the new limits. In these circumstances, the Contest Director shall select for consideration only those flights of a contestant that would be qualified under the new limitation, and shall then choose the best of the selected flights as the official flight of that contestant in that event.
For example, if the Parachute Duration event must unexpectedly be limited to one flight per contestant, and a contestant has already made two flights, the Contest Director must first select only the flights that were returned, (since in single-flight Parachute Duration, the flight must be returned); if both flights were returned, the Contest Director shall select the better of the two flights as the official flight of the contestant.
