OR...perhaps TNZ was so far ahead, they were just 'testing the waters' i.e. they took the opportunity to do some on course speed testing, to see if one side of the course was heavily favored with that current/wind combination, so if they run into that same combo in the finals, they'll already know the answer to the age old question at the top mark;
"Right or Left?"
I'm quite confident these guys knew exactly where they were going and why. The effect of current on VMG is something they got sorted out long ago.
