Apparently I never did add the July shows Salvation (CBS), Somewhere Between (ABC), and Midnight Texas (NBC) to the Cancellation Watch Scorecard, but I have them in there now. Salvation is currently at Number 30 which is slightly better than Zoo (same network) at Number 38, though the numbers for the former series have been tracking downward while the latter show as seen some improvement of late. Somewhere Between is near the bottom of the list at Number 67 which is to be expected based on its poor ratings performance. Midnight Texas is currently at Number 31 and it might survive into a second season if its ratings can hold or improve over the next few weeks. Most of the rest of the movement on the scorecard was just incidental and/or adjustments based on adding in these three shows.
The scorecard ranks all of the sci fi and fantasy shows’ ratings performance vs. their network’s ratings benchmark (see definition below). Shows at or above their benchmark should be okay, whereas those slipping notably below are getting into iffy territory.

Metric Definitions:
Rank (PW): Current rank based on the variance of a show’s season to date ratings average vs. its network’s benchmark (see definition below). The number in parenthesis is the prior week’s rank. Note that shows on the streaming services are not included because of insufficient viewership data and foreign imports like Doctor Who will not be included because they rely more heavily on their viewership in their home countries.
Series: (O) indicates the show is owned/produced by the network and/or a sister studio. (F) indicates the show airs on Friday when ratings expectations are lower. These typically just apply to the broadcast networks where they are more of a factor.
StD Avg: The show’s season to date ratings average based on the overnights for the 18-49 demographic.
Net Bench: (Network Benchmark) For the broadcast networks, this is the net’s season to date average rating based on the overnights for the 18-49 demographic for non-sports, non-special, non-repeat broadcasts (for FOX, Empire is also excluded because it counts as an outlier). For the cable channels, this is the lowest level at which a show is typically renewed by that network if there are enough genre entries on that channel to provide a decent sample. But note that with cable entries intangibles such as international and/or streaming partnerships can play an important factor in a shows survival and that is not measured here.
% Var: The percent variance between a show’s season to date average and the network benchmark as defined above. The higher the variance, the better a show is performing vs. the benchmark.
Live+7 Avg Rtg: The show’s season to date ratings average based on delayed viewing up to three days past the live broadcast. This data is not available for all shows.
Status: My assessment of the likelihood that a show will get renewed or cancelled. The statuses are Renewal Likely, Renewal Possible, On the Bubble, Cancellation Likely (plus Renewed and Cancelled/Ended)
