I haven't seen or can't imagine any good reason to look back in that scenario, as opposed to not doing it. Whether or not it cost him those few inches, I guess noone will ever know for sure. My guess is that if he had it to do over again, he wouldn't look back. It was a great race by both though...my dumb *ss was on CQ, so I could enjoy the battle without any dreams of cashing a ticket on the winner.
