Seriously Todd, how can I say they had a bad day? Undoubtedly, they're having more fun than I am this week, but they did put up their first two sevens of the regatta.
Not sure how that ranks against being protested by the RC, but I'm thinking they couldn't have thought it was a great day...
So the consensus seems to be that the answer to my question is a combination of experience in the light air. That makes sense.
