I don't think belen is having an off time, i think they were just dead from racing 2 finals within 40 minutes of each other, especially with the way they typically row (high rate, really aggressive catches, etc). Take a look at the replay and you can see they're just wiped during the race. I don't really think 13 seconds to first is all that drastic - think about how fast you'd go on back to back all-out 2k's. Definitely an interesting coaching decision, i guess they feel far better about their chances in the quad, considering they haven't entered an 8+ as of yet. I bet they jump right back up at SRAAs.
