  "scope": "Selected professional-writing, consulting and developer experiments; no pooled workforce estimate",
  "geography": "Study-specific recruitment; not a representative global worker sample",
  "observation_period": "2022–2025 experiments; institutional updates checked through September 2026",
  "editorial_owner": "Workspace369 editorial team",
  "review_cadence": "Review quarterly and when a cited producer releases a replacement study. Next editorial review: December 2026. Retain historical model versions and observation dates.",
  "attribution": "Reported observations belong to the original producers. Workspace369 is responsible for the compilation and explicitly labeled calculations, not an original survey.",
  "methodology": [
    "This is a selected evidence comparison, not a systematic review or meta-analysis. Studies were included for identifiable tasks, original-producer evidence and clearly stated outcome definitions.",
    "The writing and consulting figures use their research institutions’ public summaries of published studies. The coding paper and METR report provide original experimental detail. Working-paper and published versions are not mixed.",
    "Measured outcomes and perceived speedups carry separate evidence labels. The time-index calculation uses only measured completion-time changes; survey beliefs are excluded from it.",
    "Model versions and study dates remain attached to the findings. We checked the METR follow-up and retained its warning about the reliability of newer estimates."
  ],
  "limitations": [
    "Selected experiments cannot establish a universal AI return on investment. Different tasks, control conditions, participants and quality tests prevent a defensible pooled percentage.",
    "The sample sizes describe study scope, not independent replications. Vendor involvement in the Copilot study is relevant to interpretation.",
    "Historical results do not establish the capabilities of models available today. The normalization does not include implementation costs or demonstrate sustained annual savings."
