Cavies did take visual performance on finals night with a 19.80, BD was right behind them at 19.70.
But if the captions in 2008 was averaged all three nights, then BD won visual performance by a landslide. Quarterfinals BD won with a 19.90 to Cavies 19.60............and Semi's BD popped a 20.00 to Cavies 19.80. So even with Cavies winning the caption finals night, BD would have still won by a comfortable margin.
So if it was just finals night, than yes Cavies won. But again if it was a three night average, than BD would have taken it.
Hope that helps a little brother.
