well you also have the may sweeps and though the futon critic lists N/A for 516 it is listing it for 3-3-10. So maybe they did what they thought were good enough for Feb. and looking forward? I don't know, but alot of shows are repeats (heck Bones for instance last new ep 2-2, won't be back with a new one until about April. - NCIS last new ep will be 2-9, won't be back until 3-2, NCIS: LA last new ep will be 2-9, not back until 3-2) so it's something alot of shows are doing.
Now sure if it has something to do with the olympics, the superbowl, maybe the repeats brought in better ratings when they last ran. The sky and grass are going to switch colors for two minutes those nights, or the moon can't decide if it will be full or even out lol. :lol:
No clue can't help ya there but if I hear anything news worthy on it I will post it. BTW.. You're welcome.
ETA: I am not sure of this so it maybe unreliable info but explains some, but these are the dates of sweeps.
November 2009: October 29 – November 25, 2009
February 2010: February 4 - March 3, 2010
May 2010: April 29 – May 26, 2010
July 2010: July 1 – July 28, 2010
The explains some part is that most would be returning either at the end of the period or right in the middle. Again not sure if these are correct dates.
