As I noted during the USA weekend in the overnight reports, the general trend was that the ratings for USA across the board were marginally lower than Canada, a trend that is repeated in the official ratings. If you compare these official ratings to the Canada consolidated ratings, on average the race is 35,000 viewers lower, Qualifying is 9,000 viewers lower, Practice 3 is 65,000 viewers lower whilst Practice 1 was slightly higher than in Canada.
