Spotted Ratings, Saturday 2/19/11

FYI, for today these 18-49 ratings are averages of the half-hours rather than actual program ratings, which is why some of the difference-from-lead-in numbers might look a little off.

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.

Numbers based on preliminary (fast national) Live + Same Day ratings.
