Occasionally, I will miss a wall on my flip turn. It's never happened in a meet, but came up during my last meet when an official questioned me post race for barely touching a toe. During a freestyle event, is it within the rules to stop immediately and go back to touch a wall at the end of a length? Or, is the race over and might as well get out? For a short race, I'd just keep going. During a long event, I'd hate to do so, but would stop and go back so as not to risk it, if that's a possibility. Thanks.
