How fast is typical cutting in Hollywood features and how has average shot length changed, as a benchmark for pacing a shot list?

Cutting, Brunick, DeLong, Iricinschi and Candan (2012) report for 160 English-language films 1935-2010 (high box-office or, before 1977, most-rated on IMDb) that average shot length fell from about 10 s in the 1930s-40s to below 4 s after 2000 (r = -.75, all five genres); the attention-control explanation is their hypothesis. Curator qualifications: The 1,100-shots figure is stated for the earlier 150-film sample being described; the producer's 'a few hundred shots is short' framing is synthesis. Article licence is non-commercial with no alterations: quote, do not adapt figures. Climax-pacing row (E5) comes from the 2016 paper, not this one. Text only; no film analysis reproduced. Limitations: Selection rule changes at 1977. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
