One of the Chinese divers looked down in the middle of a twist and did not make the entry required for the dive. As a result, the Chinese team received no points for the dive. It looked like Dmitri Sautin hit his toes on the board and mashed his entry, but it was the correct entry for the dive, however badly executed, and he (individual) and they (synchronicity) received low scores as a result. (I'm so bummed. Sautin is one of my favorites, even if at this point in his career, he's being held together by duct tape. But at least he made the mistake himself, and there was no finger-pointing by anyone at a younger, less experienced partner.)
There are no deductions for the LP under OBO. There's no way of telling for what or how much any skater or team received for credit for any elements under OBO, because 1) each score is aggregated and 2) the scores are relative.
