Analysis
The day's leverage distribution matters more than the headline figure. The 28.1x ceiling came from Accessibility contrast-standard rollout: codified WCAG 2.1 AA contrast standard in a design system and applied uniformly across 18 repos (marketing sites, React...; the 5.4x floor was Committed + pushed 17 libs/clients to staging (per-repo test-gated, ~3,500 tests re-verified green post-reinstall); fixed Mermaid renderer bun per-file coverage.... Tasks at the top of the distribution share a shape: tightly-scoped specifications, clear success criteria, and minimal integration ambiguity. The AI doesn't need to discover anything new; it executes against an explicit target.
Tasks at the bottom run differently. They're either bounded by review-heavy work where every step gets verified, or they involve ambiguity that demands several rounds of trial and adjustment. The factor is real and informative, not a failure mode.
The supervisory leverage figure (149.4x today) tracks something orthogonal to wall-clock leverage. It's the ratio of human-equivalent output to human prompt-writing time. It stays high even on lower-leverage days because supervisory minutes scale with task count, not with the human-hour estimate; a 20-minute task and a 4-hour task can both be specified in two minutes of human prompt-writing.
Across the 19 tasks, the day produced roughly 2.9 weeks of senior-engineer-equivalent throughput in 7.8 hours of model wall-clock. That ratio is the practical answer to the question of how much output a single operator can move per day when the model handles the execution and the operator handles the direction.
