The scorecard ranks all of the sci fi & 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.
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.
Variance: The 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 network mean.
Live+3 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. Last year I had the Live+7 delayed viewing, but the availability of that data was very spotty so I am shifting to this metric.
Cancel Alert: My prediction of the likelihood that a show will get cancelled. From least to most likely the statuses are Low, Moderate, Medium, Elevated, and High.
