The season two premiere of Legend of the Seeker averaged 2.583 million viewers the weekend of November 7-8 with a 1.7 household. By household rating it was ranked tied for 45th out of 129 syndicated shows measured for the week.
The 2.583 million was the average audience, but you might wind up seeing the number 3.528 million thrown around, too. That's the gross average audience for the premiere. Gross average audience is a metric commonly used in syndicated ratings where viewing of repeat broadcasts during the measured period *is* counted. But for apples-to-apples purposes of comparing to other shows you should use the 2.583 million number.
