What the other guides get wrong
Spec sheets publish “15 seconds” or “60 seconds max” as though it were the technical ceiling. Meta's is 241 minutes. Those shorter figures are advice about attention republished as a limit — which is the same mistake as printing a recommended headline length as a hard cap.
