Long-form content repurposing time saved

Benchmark range

Lower bound: 1 hours. Median value: 1.5 hours. Upper bound: 2 hours.

Measurement period: per long-form source asset repurposed into a week of post drafts.

Methodology

Triangulated from published research rather than from measured deployments of this skill. Content Marketing Institute, citing Orbit Media's annual blogger survey, puts production of one 1,400-word blog post at three hours 48 minutes, which anchors the manual cost of long-form drafting; a week of five to eight short channel-specific drafts plus the planning pass is treated conservatively as three to five hours of manual work. Two peer-reviewed studies bound the reduction achievable on writing tasks: the Science randomised experiment on mid-level professional writing found a 40% time reduction with an 18% quality increase, and a within-subject study of 27 graduate students found a 56.7% median reduction. CaseLedger applies the lower 40% figure to the lower end of the manual range and discounts further for mandatory human review, giving 1-2 hours saved per source asset with a 1.5 hour median. MIT Sloan's finding that AI-written job posts were 15% less likely to lead to a hire is the reason no credit is taken for removing review, and Content Marketing Institute's finding that 76% of marketers do the work of more than one job explains why the saving matters without inflating its size.
