Post race OCS

 Another common request for redress is when a competitor is scored as being OCS or UFD and they don’t think they should have been. Every sailor should get in the habit of checking the official notice board once they come ashore, to A) to check they are not listed in any protests and B) once the results are posted that they have been scored correctly. If at this point you see an OCS or UFD score against your name and you think it is wrong, your first move should be to speak to the Race Officer and ask to review the tape recording of the start. Often this can solve the issue if you hear your number clearly called out prior to the gun, but if the race team failed to record the premature starters on tape or video, then you have more of a case for requesting redress. However, getting a fellow sailor who wasn’t called over to witness that you were behind them on the line doesn’t always work. At a recent Topper World Championship, one such request for redress was heard and a witness produced who confirmed they were ahead of the boat in question when the gun went. When the Race Officer came to give his evidence, he thanked the witness for confirming his position and said that on the individual recalled start there was another boat was spotted over the line that the starter couldn’t identify. As the witness had now confirmed which boat that was, they were now scored as OCS too and the protest committee refused the original request for redress! 
Taken from an article I was reading.
I would have presumed if the RO had known there was a boat that was OCS and they had no number for it that it should have been a General Recall?
