Spotted Ratings, Sunday 2/20/11

Despite ABC's lineup rallying week-to-week from the Grammy shalacking, that still left the latter two shows well below their averages this season. Same goes for Fox's animation. The former two ABC shows did get back above average, though. Undercover Boss and probably (missing a few early data points) The Amazing Race hit series lows. SNL specials remain an unbelievably reliable grabber of decent ratings.

KEY
A18-49 - From Nielsen. Adults 18-49 rating. Percentage of US TV-owning adults 18-49 watching the program.
Share - From Nielsen. Adults 18-49 share. Percentage of US TV-watching adults 18-49 watching the program.
Lead - Calculation. Percent difference from lead-in program.
Last - Calculation. Percent difference from previous original episode.
LeLa - Caclculation. Percent difference between the show's lead-in and its lead-in for the previous original episode.
Comp - Calculation. Competition. Total rating of all broadcast programs airing against it.
HUT - Calculation. Phrase commonly known as "Households Using TV," but in this case it's actually "Adults 18-49 Using TV." Percentage of US TV-owning adults 18-49 who are watching any TV in that timeslot. A rough approximation based on all ratings/shares in the timeslot. More on this later.
bcShr - Calculation. Broadcast share. Percentage of US national big-5 broadcast TV-watching adults 18-49 watching the program.
Avg - Calculation. Percent difference from the show's average demo for previous original episodes this season.
Rank - Calculation. The rating's rank among the show's original episodes that have aired so far this season.

oR = Out-of-timeslot repeat. I plan on doing the ranking/average things with repeats, but only in-timeslot repeats. (Will become more applicable once we're out of sweeps.)

Will probably develop more disclaimers if this develops further, but the one that jumps out for now is that the stats in blue will be less accurate because for now I'm counting every program as if it maintains that same rating throughout each half-hour of the broadcast. That is almost always not the case in reality.
