What length, act and scene-count figures do Baker, Esenwein and Leeds, Phillips, Lutz, Munsterberg and Aristotle give, in which medium, and do they agree?

Concordance (code_derived_inference). Figures belong to different media and years and mostly cannot be pooled. Stage (Baker 1919): 3, 4 or 5 acts, a 2 to 2.75 hour evening, 5-15 minute intervals, no rule for act length. Silent film: Esenwein and Leeds (1919 ed.) and Phillips (1914) agree on a 1,000-foot reel with 25 to 50 scenes (Phillips elsewhere 25 to 60, and 75 to 200 scenes an hour, which his own 20-minute reel makes 75 to 150). Lutz (1920) gives 16 pictures per foot and one foot per second (a 16.7-minute reel) for animation timing and no film length in Ch. X. Munsterberg's 170 scene changes in ten minutes is 5 to 14 times Phillips's rate and unchecked. Aristotle gives no numeral for length (tragedies per poem, 'embraced by the memory'). Archer and Forster have no record. Checked arithmetic and internal tensions are listed. Curator qualifications: Arithmetic is correct. Phillips 25-50 per reel at 20 min = 75-150/h. Lutz 1,000 ft at 1 ft/s = 16.7 min, giving 90-180/h. Munsterberg 170 per 10 min = 1,020/h, 5.1-13.6x Phillips's 75-200. Baker's 2.5 h needs the assumed two intervals at the 15-minute figure. All are worker arithmetic over figures from different media and years; none is an author's claim. Evidence status: curator/producer inference or synthesis from the cited sources (code read, not executed, where code is cited); correlated desk review (Claude); not independently reviewed.
