Precision Duration Competition comprises three events open to any single-staged model rocket. The purpose of this competition is to accurately predict the duration that a model will achieve.
The contestant must predict the duration in seconds that the model will achieve. This Predicted Duration shall be recorded on the flight card and given to the Contest Director or his/her deputy prior to any official flight by the contestant at the meet. The minimum duration prediction allowable is 30 seconds.
The Contest Director shall set the target duration when the meet is sanctioned. This value shall appear on the sanction form and all appropriate contest information. The target duration shall be a multiple of 5 seconds between 30 and 120 seconds. All contestants shall attempt to achieve this same Set Duration.
The Contest Director shall randomly select the target duration just prior to when the event is flown, by draw, dice, or other random device. The target duration shall be a multiple of 5 seconds between 30 and 120 seconds. All contestants shall attempt to achieve this same Random Duration.
