*-week 4 Earl/Office finales not included; I don't want to compare a half-hour vs. an hour and couldn't find half-hour breakdowns on the Earl/Office 2008 finales... if anybody has those numbers, let me know

Note: Averages don't necessarily include every sweep airing of a show. I'm only including an airing if the show (or two shows being compared) aired both this year and on the year-ago evening.

Didn't want to get too deep into the bureaucracy on the PIF post, but I will add another note that the comparisons between two different shows are included in these lists only if there is more than one instance of that comparison. On the other hand, ALL comparisons between the same show will be included, even if there's only one data point.

Also, these are ranked from best to worst, not separated by network as in the daily posts. But that was not too hard to figure out. ;-)
