12 tasks. June 22, 2026 closed at 20.2x weighted leverage across 124.7 human-equivalent hours in 371 minutes of wall-clock time. Supervisory leverage came in at 213.8x.
That is 3.1 weeks of human-equivalent throughput in 6.2 hours. The ceiling was 140.0x; the floor was 2.4x. 6 of the 12 entries came from a single project.

Analysis
The highest factor of the day came in at 140.0x and the lowest at 2.4x, a spread of 58.3 times between the two. That is a wide range for a single day, and it usually means the day mixed mechanical work with work that needed real judgement.
The largest single entry accounted for 14.0 of the 124.7 human-equivalent hours, or 11 percent of the day. No single task dominated the total, so the weighted average is representative.
Supervisory time was 35 minutes against 371 minutes of execution, a ratio of about 1 to 11. Supervisory leverage of 213.8x is the figure I find most honest, because it measures the hours I actually spent rather than the hours a machine spent on my behalf.
Every figure here is recorded at the time the work is done rather than reconstructed afterwards. The human estimate is my own judgement and carries the uncertainty that implies; the minutes and tokens are measured. The full dataset, including this day, is available for download.
