Perhaps they were testing techniques that would carry over.
After watching that pathetic "foiling tack" I'd say they need to do a lot more testing before they are ready to defend the Cup. I was expecting to see a close match. But the Kiwis just seem to own the 3rd leg of the race. That leg is probably responsible for 90% of the overall time margin they have won by.
There was some speculation yesterday that the Oracle boat was simply harder to sail. I can't help but wonder if the loss of de Ridder has had something to do with it. Whatever, unless Oracle pulls out a miraculous recovery, the Cup is headed Down Under. But I'm okay with that. From what I've seen, the Kiwis will appreciate the win much more than the Americans would. Still, I'd like to see a close competition.
