Secret control
A timing point not announced to the crews. It records the transit time unnoticed and thus reveals deviations from the prescribed target time or average speed.
A secret control is a timing point whose exact location the crews do not know. Unlike an open time control, it is not announced; it records the transit time unnoticed. This checks whether the prescribed target time or average speed was kept over the whole sector – not only at known points. In the Italian prova di media these points are called controlli or rilevamenti segreti and are the heart of the scoring.
