How We Counted & Methodology
We analyze consecutive broadcast seasons (Season N to Season N+1) of television series with at least 3 seasons cataloged. Both the prior and subsequent season must have at least 3 episodes, and every episode in both seasons must have at least 50 user votes. Rating delta is computed as Mean(Season N+1) − Mean(Season N).
