Strength of Slot 

also known as Strength of Time Slot, is a term used, often in televation ratings circle, particularly network tv ratings, in describing the competitiveness of a timeslot. The more competitive the slot, the harder it is for shows, especially those on lowly network stations such as CW, to garner high viewership, either in the 18-49 age group or total viewers. Many shows get canceled due to being in difficult time slots as well as facing off against much higher rated shows in the similar slot.

Duante: Monday nights are typically very poor for the CW as they have to go up against shows such as NBC's The Voice and Blacklist, two shows which often pull 3.0 or higher ratings for the 18/49 age group and 9+ million total viewers. The Strength of Slot is pretty high and competitive

MUA Nicole Kristen Williams: So true, The top show on CW is lucky to pull a 1.4 in 18-49 much less a 2.0 or 3.0+.

Strength of Schedule 

term used, often in America Football, particularly College Football, in describing the difficulty of opponents a team has faced. The harder the S.O.S., the better as the team is more likely to be pardoned for losing games if they typically face better opponents.

Ohio State beat out Baylor and TCU to grab the fourth and final spot of the 2014 college football playoffs because Ohio State had a better strength of schedule as well as out of conference schedule. So though all three had lost one game each, the committee believed Ohio State's strength of schedule warranted them being awarded the final spot in the rankings.
