It is all part of the game I guess.
I doubt Styles wouldn't have done the same if the roles where reversed, IMHO it was a very smart tactical move by Bundy.
He did the same thing at the '07 worlds in Aus where he matchraced Booth down the fleet in the final race to win the title.

Judging by the last thing I saw of Styles I think he was pretty much over it.
We where literally kicked out of the little restaurant/bar at the beach at midnight,
some Aussies wanted to buy the place but the owner didn't go for it! (I think after a week he was happy to see the catsailors go to be honest).
