Nineteen tasks. May 11, 2026 weighted to 37.2x leverage across 473.5 human-equivalent hours in 764 Claude-minutes. The day was launch-night itself plus a sustained accessibility-audit-and-remediation push across the customer product and 8 marketing-site fleet members. Late-night security audit, real-time fabric refactor, and the inevitable post-launch infrastructure fixes rounded it out. Supervisory leverage closed at 263.1x.
11.8 weeks of human-equivalent throughput in 12.7 hours of Claude wall-clock. The 240.0x ceiling came from WCAG 2.1 AA accessibility audit across 9 properties (a web client + 8 marketing sites) — ~120 concrete findings with file:line refs, severity grouping, cross-cutting themes, and...; the 7.6x floor sat at Launch-night batch: fix admin delete lockup (a cache layer purge timeout), unblock an API service CI build (ruff lint), kill a frontend library 401 retry storm, rebuild + upload....

Analysis
The day's leverage distribution matters more than the headline figure. The 240.0x ceiling came from WCAG 2.1 AA accessibility audit across 9 properties (a web client + 8 marketing sites) — ~120 concrete findings with file:line refs, seve...; the 7.6x floor was Launch-night batch: fix admin delete lockup (a cache layer purge timeout), unblock an API service CI build (ruff lint), kill a frontend l.... 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 (263.1x 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.
May 11 was the actual launch day. The 240x ceiling on the WCAG audit task is a useful data point: deterministic audit work against a defined standard is where AI leverage maxes out, because the specification is external and the checker is mechanical. Launch-night fixes ran lower-leverage because every change needed live-system verification.
Across the 19 tasks, the day produced roughly 11.8 weeks of senior-engineer-equivalent throughput in 12.7 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.
