Does Phillips (1914, Ch. IV) give any length or number limits for captions, inserts and other devices, and do the chapter's own examples fit the limits stated elsewhere?

1914 practice (Phillips) negative result, bounded to Ch. IV: no word, footage, count or frequency limit appears; limits are qualitative ('too frequently', 'dangerously long', 'mercilessly'). The 15-word caption and 20-word insert figures are in Ch. IX (cited via C3-B259-S74-05). A code-derived count of the chapter's printed examples shows every caption counted at 12 words or fewer, but letter inserts of 20-21 and 35-36 words, so Phillips's own Example 17 exceeds the Ch. IX insert figure unless abridged. Curator qualifications: Negative for Ch. IV confirmed. Cross-link: Ch. IX's 'every word means a foot of film', read with the about 1 ft/s rate (Lutz; Esenwein and Leeds Ch. XIII), makes a 15-word caption about 15 s of screen time. This is curator arithmetic, not Phillips's statement. 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.
